Chapter 3 – Meeting with Kamokura

Today, the campus cafeteria is bustling.

Ishida went to see his professor to submit an assignment, and I headed to the cafeteria first.

(It’s really crowded. Maybe because of the exams next week?)

Typically, as exams approach, people who usually don’t come to campus start to show up.

(Is there an empty seat here?)

I walked around the cafeteria with a tray of yakitori donburi, but every table was full.

After circling twice, I spotted a table for two in the corner with a man sitting alone.

(Alright, maybe I can sit with him. It seems he’ll be finished eating soon. If Ishida comes later, it shouldn’t be a problem.)

I approached the table and asked, “May I sit with you?”

The man, who was looking down, lifted his face.

When I saw his face, I caught my breath.

(Kamokura Tetsuya…)

He’s the man who took Karen, my most hated ex-girlfriend.

And he’s Touko-senpai’s ex-boyfriend.

That Kamokura Tetsuya.

When he saw my face, his expression turned into one of dislike.

I immediately turned around with my tray.

Really, there’s no way I can eat while looking at this person’s face.

However, as I was about to leave,

“Wait a moment,”

Kamokura called out to me.

Without thinking, I stopped. I didn’t expect him to speak to me.

“Is there something I can help you with?”

I gave a response, though my disdain was apparent.

“All the other seats are full, and there’s nowhere else, right? Just sit down.”

“I don’t want to sit with Kamokura-senpai. I’ll find another place.”

“Oh, what, are you scared of me? Still as weak as ever, you.”

Kamokura smiled with an annoying smirk, though he looked handsome.

But I didn’t want to appear afraid of him.

“I actually wanted to talk to you a bit. Now, sit down.”

Kamokura said so, pointing to the seat in front of him.

I didn’t want to seem like I was running away, so I sat down in front of Kamokura.

“What do you want to talk to me about?”

I asked. I had no intention of touching the food. Kamokura lifted his glass.

“You seem to have been working hard for Miss Muse, huh?”


“You’re rumored to have gotten over Rindou Akane, is that true?”

“It’s not that I got over her. Besides, we didn’t choose Rindou-san as a target. She saw Touko-senpai as an enemy for no reason.”

“That’s so like you.”

Kamokura took a sip from his glass, perhaps to moisten his throat before starting a serious conversation.

“So, what’s your relationship with Touko after that?”

(Of course, this is about Touko-senpai)

“We meet occasionally.”

I answered coldly.

However, Kamokura laughed through his nose after hearing my response.

“Is that all?”

He’s still an unpleasant person.

He always talks in a way that belittles others.

“I don’t need to tell Kamokura-senpai about my relationship with Touko-senpai, do I?”

I gave a brief answer to quickly end the conversation.

Honestly, since that incident, I’ve felt a bit sorry for Kamokura.

Indeed, I can’t forgive him for bragging and cheating with Karen, my ex-girlfriend.

However, after finding out that Touko-senpai never had such a relationship with anyone, I could understand Kamokura’s feelings of falling into infidelity.

Especially after he was humiliated in front of many people.

And for Touko-senpai, who Kamokura had been targeting, she went to a hotel with me that night.

I can’t forget Kamokura’s look of despair that night.

(But actually, I just went to the hotel with Tōuko-senpai, and nothing happened in the end.)

But, as we talk like this, my dislike for Kamokura resurfaces.

Kamokura Tetsuya and I have never gotten along.

“Don’t make the situation more complicated.”

Kamokura looked at me with one eye closed.

He’s truly an arrogant man.

“Even so, I’m also worried about your relationship with Touko.”

“There’s no need to worry.”

“Your relationship with Touko doesn’t seem to have progressed after that incident, has it?”

I glared sharply at Kamokura.

I couldn’t speak carelessly because he guessed it correctly.

“Clearly, the hotel you visited that night is still doubtful whether you really did it or not.”

“Kamokura-senpai doesn’t need to know about that. What’s the basis for saying such a thing?”

Then, Kamokura looked at me seriously and leaned in.

“I’m not sure Touko would easily give herself up like that. Because Touko can’t forget that man.”

“That man?”

Without thinking, I also responded. Does Kamokura know something about Tōuko-senpai that I don’t?

“You don’t know about it either, huh?”

This time, Kamokura looked surprised.

“It’s the man who was Touko’s private tutor. His name is Sanjou Yoshito. He graduated from the Faculty of Medicine at the University of Tokyo, and he’s the person Touko has liked since she was in third grade of junior high school. It seems he was her first love.”

Touko-senpai’s private tutor. Liked since the third grade of junior high?

A feeling ignited within me.

Was it jealousy, worry, or anger?

But I couldn’t explain that feeling to him.

Without paying attention to my condition, Kamokura continued his story.

“For four years from the third grade of junior high to the third grade of high school, Touko studied with that man as her private tutor. And even after entering university, she continued to harbor feelings for him.”

Tōuko-senpai, for five years, remained fond of the man she liked…

“But, at the end of her first year at university, Touko finally had the courage to tell Sanjou about her feelings. Unfortunately, Sanjou had just gotten a girlfriend. After finding that out, Touko couldn’t confess her feelings. That’s when I was able to take advantage well.”

…On the night we discovered the infidelity between Kamokura and Karen.

Why I asked why she was in a relationship with Kamokura, Touko-senpai answered like that.

Behind that answer, was there such a reason?

“Sanjou is the child of Touko’s parents’ friend. Touko’s parents also really liked Sanjou, and they wanted Touko to marry him in the future. Well, a relationship approved by both parties.”

I was stunned to hear it, and Kamokura continued his story.

“So that’s their relationship. Besides, Touko said that several times they were alone at home and that she studied with Sanjou as her private tutor. For Touko, that was a great opportunity. And even though they weren’t really dating, it wouldn’t be strange if they became a couple.”

“All of that is just Kamokura-senpai’s fabrication.”

“But the possibility is entirely there. And thinking like that, everything starts to make sense.”

“It’s still not clear.”

“I have enough experience with women, you know? Why do you think I can make many women fall for me? Because I distribute personality patterns and types of women’s likes, then pretend to be the man that the woman wants. I’ve analyzed that data and made predictions. And my analysis of women has never been wrong.”


“Think about it reasonably. A beautiful girl with an ideal body likes you a lot. And you meet just the two of you every week. For four years. You must talk about a lot of things to each other. Even Sanjou knows that Touko really likes him. In a situation like that, in the summer wearing thin clothes, what if you both are together? At home, there’s no one else. In such a situation, if the mood becomes good? Touko herself has been harboring her feelings for four years. And both parents hope Touko will marry Sanjou. It’s impossible to refuse. The private tutor made them so close. There’s a comfortable bed next to them. In such a situation, if one of them lets go of their control? Of course, both of them…”


I accidentally shouted.

People around looked at us curiously.

I glared sharply at Kamokura.

“Even though you’ve broken up, to say such things about an ex-girlfriend… You’re really the lowest.”

Kamokura seemed briefly defeated by my determination, but soon smirked sinisterly.

“I’m just telling you as a warning, you know.”

With that, Kamokura stood up, holding his finished tray.

“It could be that you and I are being played by Touko.”

Leaving those words behind, Kamokura left.

After Kamokura left, I remained sitting in the same posture for a while.

…Touko-senpai’s first love, an elite from the Faculty of Medicine at the University of Tokyo…

…He was Touko-senpai’s private tutor. Of course, there was a time when they were just the two of them…

My mind drifted to unpleasant thoughts.

I didn’t touch the dish in front of me, just enduring any impulse.


The called voice made me jump.

When I lifted my face, Ishida was standing in front of me.

“What’s happened to you?”

But at that moment, I couldn’t immediately say anything.

“Kamokura was here, wasn’t he?”

Ishida, looking in the direction Kamokura left, asked.

I nodded without speaking.

“What did you guys talk about?”

He sat down and asked after taking his seat.

“Kamokura talked about…”

I recounted about ‘the private tutor who was Touko-senpai’s first love.

“Lately, I’ve come to understand. All this time, I’ve been wondering why Touko-senpai was dating Kamokura. Now I understand the background.”

“Clearly, someone who’s just had their heart broken tends to be vulnerable.”

Ishida agreed, nodding, but his expression was complicated.

“Touko-senpai, can she still not forget that private tutor…”

Ishida said after a moment of silence.

“If she’s liked him for five years, it can’t just be forgotten so easily. And especially since it ended without her expressing her feelings…”


I wanted to continue those words, but I held back.

If I were to speak them out loud, I felt I would stoop very low.

But Ishida wouldn’t let me keep silent.


“Ah, it’s nothing.”

“If you don’t want to say it, that’s also fine. But sometimes, saying it out loud can provide relief. Maybe I can help too.”

“Yes, you might be right. Holding these feelings inside won’t solve anything.”

Thinking so, I decided to pose a hesitant question to Ishida.

“What if Ishida were a private tutor for a beautiful girl and she liked Ishida very much, what would you think?”

Ishida thought for a moment.

“Hmm, it depends on the person. If she’s still a middle school student, that’s definitely off-limits. But if she’s a high school student?”

“It’s quite common for college students and high school students to date. If she likes you very much, and you meet regularly every week, even alone… it’s not strange if feelings develop, right?”

Hearing that, I grabbed my head with both hands.

“Ah~” a long sigh escaped.

“So, that’s it. Yes, it must be like that.”

Ishida looked surprised.

“Wait. That’s just my speculation. And it doesn’t necessarily mean Touko-senpai would experience the same.”

“On the contrary, are you sure you could restrain yourself if you were in Touko-senpai’s position?”

Ishida looked surprised.

“Perhaps, I’m not sure…”

“Of course. Touko-senpai’s body is that beautiful. It’s natural.”

We remained silent during this lunch.

Finally, I said, “If Touko-senpai can’t forget her first love, I can understand her attitude all this time of drawing a line.”

…Maybe I am also being played by Touko-senpai…

Kamokura’s last words still echoed in my head.

The next day, in the afternoon, Meika-chan came to my house again.

Meika-chan said, “Last time, it wasn’t valid because we weren’t alone.”

Since it’s a regular day, both my parents were at work, so today it was just the two of us alone at my house.

As before, we focused on math and physics lessons, which she found difficult.

Meika-chan wore her white summer school uniform today.

The summer school uniform, if she leans forward, her chest area becomes visible.

And because it’s after school, maybe because of that, a slight scent of sweat is detectable when in a closed room.

I am not a fan of any particular smell, but that scent wasn’t unpleasant at all.

Looking at Meika-chan’s serious face, I felt the wonder of attraction changing from a girl to a woman.

(Did Sanjou-sensei, Touko-senpai’s private tutor, see Touko-senpai in the same way..?)

Thinking about it, a vague feeling, like jealousy, panic, and anger, emerged again within me.

Meika-chan said that she likes me.

Isn’t this situation somewhat similar to Touko-senpai and Sanjou-sensei’s?

(If only I hadn’t met Touko-senpai, and if I didn’t have a girlfriend… Would I reject Meika-chan’s approach?)


I really like being called that by Meika-chan.

“Is something wrong?”

Her sharp eyes stared straight at me.

I was inexplicably happy.

I felt as though she could read my mind.

“It’s nothing.”

I turned my face away from her.

“So, this is problem 205, about the cross product in vectors: ……”

Meika-chan moved closer to me holding the workbook.

It was because I was teaching her, but even then… her body was very close to mine.

That’s why Meika-chan’s soft breasts touched my arm.

(I wonder if the same thing happened to Touko-senpai and her teacher.)

Since high school, Touko-senpai has had an extraordinary style.

What if the same thing happened to the more senior Touko…?

Then what about Sanjou? ……

When I thought about it, ……


I accidentally pushed Meika-chan’s shoulder.

Meika-chan turned her eyes.

After I did it too, I thought, “Oh crap.”

“Oh, no. I just came back from campus, and I might be sweating, so it will smell.”


“And, look, it’s just the two of us in the house today. I think it’s not a good idea to be too close ……, you know, it wouldn’t be good if something weird happened.”

For a moment, Meika-chan looked stunned, but she soon smiled.

“I understand. After all, Yuu-san is a serious person.”

But her smile looked a bit sad.

(No, it’s not like that. ……)

It was sad to say it because her behavior was caused by something else.

“I also like that part of Yuu-san.”

Her straightforward words and gaze hurt me.

That night in bed, I couldn’t sleep.

The reason is …… still about Touko-senpai’s tutoring.

Today, when I was teaching Meika-chan, I pushed her.

What if the opposite happened and I hugged her tightly?

Meika-chan is very cute. She’s truly a beautiful girl.

I might have liked her too if not for Touko-senpai.

If that situation …… happened, I don’t understand what would happen.

The same thing might not necessarily have happened between Touko-senpai and Sanjou-sensei, her teacher.

No, if I think about it normally, I have to think that something must have happened.

In high school, Touko-senpai was a beautiful girl with her beauty and style already perfect.

Touko-senpai looking at Sanjou with a heated gaze.

Just the two of them at home. No one else in the house.

Their bodies close to each other. They were so close that they touched or didn’t touch. ……

“Sensei, I love you,” Touko-senpai sweetly said as she confessed her love to her teacher. ……


I shouted, and raised my upper body from the bed.

I don’t want, I don’t want. That’s …… something Touko-senpai was capable of doing.

But the more I thought about it, the more what Kamokura said seemed like reality.

And because he was referred to as a private tutor, he must have come to Touko-senpai’s house regularly, once or twice a week.

If once or twice, I might be able to resist being tempted by a girl as beautiful as Touko-senpai.

But if every week, and for four years, then ……

And even if Touko-senpai, who is serious-minded, might let herself be seduced by someone who was her first love and whom her parents wanted her to marry if possible, right?

I spent every day after that thinking about the worst possibilities.

[POV Touko] Before Touko’s Birthday

Today is the 2nd of August. Tomorrow is my birthday.

And after the final exam is over, Isshiki-kun said he would celebrate my birthday alone with me.

Just the two of us…

Even though there’s an exam tomorrow, I can’t focus on studying.

This has never happened before…

Actually, a few days ago, Kazumi called me.

“Touko, I heard you’re going on a date with Isshiki-kun on your birthday?”

“Eh, who said that?”

I spontaneously replied like that. At least I hadn’t told anyone.

“Ishida-kun told me. I talked to Ishida earlier, ‘Yuu promised to celebrate Touko-senpai’s birthday with her,’ he said.”

Hmm, Kazumi. I hope she doesn’t tell anyone else.

But from this conversation, maybe it was before he invited me to the cafe.

“Then Ishida spilled the beans. ‘If possible, to confess his feelings to Touko-senpai at that time,’ he said!”

“Eh!” I accidentally shouted out loud.

But now that I think about it, there was indeed such an atmosphere.

From Kazumi lately, I felt she was trying to make a decision regarding our relationship.

It seems she was timing it carefully.

…If we go on a date alone after this, maybe he will express his feelings…

I have a premonition like that. And ‘the next date’ might happen on my birthday tomorrow.

“Touko, what if Isshiki-kun confesses his feelings to you?”

Kazumi asked somewhat worriedly.

She calls herself ‘my guardian’ and often checks on my male-female relationships.

“Hmm, I don’t know until the time comes…”

“Again, you’re always like that. If Isshiki-kun finally dares to express his feelings, and Touko feels the same, then accept it with conviction.”

“I’ve always thought so since the beginning… But it’s rare for Kazumi to talk like this.”

She tends to be cautious about my opposite-sex relationships.

According to Kazumi, I tend to be ‘easily deceived by bad men.’

When I dated Tetsuya, she was displeased even though I told her later.

Indeed, it was a failure…

“If it’s with Isshiki-kun, there won’t be risks like that. More importantly, it seems he will cherish your feelings, Touko.”

Indeed, I feel he always pays attention to me.

But on the contrary, I feel he is not too actively enthusiastic.

“So, what about it, Touko? Will you accept Isshiki-kun’s confession?”

“Eh, eh, accept?!”

“Don’t you like Isshiki-kun?”

“It’s not like that, it’s not because of that. But…”

“Tomorrow is your birthday, right? Don’t drag on dating, so if he confesses his feelings romantically, it’s okay to go straight to the hotel, you know!”

“To, to the hotel, that’s impossible, like that!”

“Oh, you two have already been to a hotel, even though nothing happened.”

I could hear Kazumi’s laughter through the phone.

On the other side, I imagined Kazumi’s funny expression.

Little by little, I started to dislike Kazumi.

“Well, even if it’s a joke, stop it for a while with Isshiki-kun. Don’t let him keep waiting.”

“I’m not making him wait! Even though I don’t have such thoughts…”

“Even if Touko doesn’t have such thoughts, it appears so to those around you. Someday, Isshiki-kun might distance himself from you. Men also won’t keep waiting for a flower that’s too high. He is quite popular with women.”

(What, too high a flower. I didn’t mean to feel superior.)

I try to remember his usual behavior.

But maybe because of Tamami’s words, his polite face when talking comes to my mind first.

“Does Isshiki-kun really like me?”

I spontaneously uttered those words.


“Oh, no, that… I was just thinking… If he likes me, he might be more active… He has never been like that before.”

“It’s because you’re putting up a fence, right? This is a good opportunity. On your birthday date, slightly lower your defenses?”


“I’ve said it before, relationships between men and women are about timing. But such timing doesn’t always come around many times, you know.”

“Today, Kazumi is really supporting Isshiki-kun, huh?”

“I like him too. And more importantly, I’m also interested in Touko.”

“In me?”

“You continue to be seen as ‘a woman who is too proud’ until you graduate from university, then head towards thirty, and maybe even until forty.”

“That’s very rude, you know. You’re really saying terrible things.”

“I won’t be able to accompany you till then, though.”

Once again, Kazumi burst into loud laughter.

“Thanks for the advice! I’ll keep it in my heart.”

I said so while hanging up the phone grudgingly.

Since then, “maybe Isshiki-kun will confess his feelings to me on my birthday” has become a thought I can’t ignore.

(If… Isshiki-kun really says he wants to date me, what then?)

I propped my chin on the table.

A restaurant on the top floor of the hotel. We were engrossed in conversation…

Towards the end of dinner, he quietly gives me a present…

Isshiki-kun with serious eyes says, “Please date me.”

I just nod, “yes”…

Then he says, “A room is already booked tonight. Would you come with me?”…

I might not be able to answer at that moment…
He hugs my shoulder tightly, saying, “I don’t want to let you go,”

I will be hugged by him, going to the hotel room with him…

“What am I thinking!?”

I inadvertently scolded myself.

I’m not a woman who’s so easily swayed!

Although I have been asked out on dates by Tetsuya and other men several times, I have always firmly refused.

(But Isshiki-kun, he’s different from other men, isn’t he?)

A voice inside me says that.

(If… that happens…)

Am I already good enough like this?

Isn’t it strange?

Even though I haven’t exercised leading up to the exams, don’t I look fat?

Even though lately, I’ve been afraid to step on the scale…

Are all my underwear neatly arranged?

I can’t just leave that worry alone.

I leave the table, open the drawer where my underwear is stored.

(If the underwear doesn’t match, it might look strange…)

Usually, I care about comfort and not showing through clothes, but for this date, it’s a little different.

I take out several sets of underwear from where I store them

I choose a set of rarely worn bras and panties, laying them out on the bed.

Black with elegant lace, red with lace and mesh, also soft purple, light blue, and pink. I arrange them all on the bed.

“Black bras and panties seem expected. But this red one, looks like I’m playing… maybe this light blue is nice? Looks clean. Ah, but the pink is also cute.”

Comparing the sets of underwear on the bed, I whisper like that.

(Maybe I should try them on first, then I’ll know, right?)

I undress and put on each bra and panty set, then look at myself in the mirror.

“Ah, black does seem nice. But this is the first time, it seems not quite right.”

“This red color… oh no, this is a T-back. Right, I bought it for thin long pants, so the lines wouldn’t show. And the bra I bought is a half cup.”

“Hmm, this purple lace is beautiful, but it also seems a bit hopeful for something… finally, light blue or pink, then?”

At that moment, I was startled.

“No, wait a minute. Doing something like this, it seems like I’m really expecting Isshiki-kun to take me to the hotel! Besides, it’s not possible to go straight to the hotel after a confession of love! Wait, wait! Everything is canceled! All that I’ve brought up until now, canceled!”

Saying so, I hurriedly put back on my casual clothes.

My face heated up.

Doing everything by myself, getting too excited by myself, feeling embarrassed by myself, how foolish of me.

Even so, looking at the lingerie scattered on the bed, I thought.

…Tomorrow, will Isshiki-kun really confess to me?
