When I Lent 500 Yen to a Friend, He Sent His Sister as Collateral, but What Should I Do? Chapter 7

Living with My Friend's Sister Just Like That


Chapter 7: Living with My Friend’s Sister Just Like That

The next day, we visited the café “Kizuna” again.

“Good afternoon, everyone!”

“Akari, welcome! My goodness, you look so cute today! Can I rub my cheek against yours?”

“Ruri, please refrain from overly intimate contact with the customers.”

I had to stop Ruri as she actually tried to hug Akari.

Though she threw a childish tantrum, I ignored it. I had a promise to keep today.

“Welcome. Is it just for one?”


“Understood. Please come this way.”

It was just past two in the afternoon when Akari visited the café during a quiet time. I led her to her seat.

I displayed a level of gentlemanly behavior I normally wouldn’t, as per her request… which was a bit embarrassing for me.

Yesterday, after returning home, Akari and I discussed what to do when I had to work.

She initially wanted to work at the café too, but with three staff members already, any more would shorten the café’s lifespan.

However, leaving Akari alone at home would make our previous discussions pointless.

So, I suggested an alternative – on days I was working, if Akari didn’t want to be alone at home, she could come to the café as a customer around two in the afternoon, after lunchtime.

I usually work three to four days a week, from ten in the morning to seven in the evening.

Since Akari wouldn’t be at the café all day, her meals would be deducted from my salary, not burdening the café too much.

Although taking the cost of her meals from my salary caused a bit of an argument, we settled it with rock-paper-scissors. Naturally, I won.

Since Akari would be doing housework at home before lunchtime, it was only fair for me to pay.

With that settled, I seated Akari, whose eyes sparkled, and after bowing to her, I headed back to the coffee bar.

“Boss, please give me what we discussed yesterday.”


Uncle, now in full manager mode, nodded seriously.

I had already secured permission from Uncle, Ruri, and my aunt, who works diligently every day, for Akari to visit as a customer.

Fortunately, Akari had already told Ruri yesterday about “living and cohabiting with me.”

I had no idea how Ruri exaggerated the story, but they eventually concluded it was better for Akari to come to the café than to stay alone at my house.

I had also mentioned that Akari loves sweets and even adds sugar to her barley tea.

Uncle prepared a special café au lait for her, sweeter than the one I usually drink.

“Why is there whipped cream on top…!”

“……(Thumbs up)”

I couldn’t help but comment on the obvious special treatment, but Uncle maintained his stern expression and just gave me a thumbs up.

Wow… Uncle was easily swayed by a young girl. The power of a pretty girl is indeed terrifying.

Though slightly alarmed, I found it to be a good thing and didn’t object.

I placed the special café au lait prepared for Akari on a plate and brought it to her.

“Sorry for the wait. Here’s your iced café au lait.”

“Wow… it even has whipped cream on top!”

Her eyes lit up in delight!

I naturally turned and gave Uncle a thumbs up.

The usually serious Uncle now smiled and returned the gesture.

It seems the old man was completely charmed by the young girl.

“Here I go!”

Akari, her eyes sparkling, inserted the straw into the whipped cream and sipped the special café au lait prepared for her.

“Mmm! This coffee is super delicious! Sweet to the heart, and rich and fragrant!”

As Akari praised the drink, snapping fingers were heard from the coffee bar. Uncle…

“I heard you like sweets, so I adjusted the flavor for you. Do you like it?”

“Yes, I love it!”

“This one’s on the house!”

Suddenly, the usually quiet Ruri chimed in.

Then she placed an incredibly fluffy-looking chiffon cake on the table.

“Hehehe, this is my special freshly-baked chiffon cake! I usually bake the cakes in advance, but today I timed it so it would be fresh out of the oven just for you!”

“Ruri, I was wondering why you were so quiet today… so this was why…”

“Of course! I was busy preparing the cake for Akari. Come on, try it!”

“Can I really accept this gift?”

“Of course you can!”

Ruri suddenly gave a thumbs up, her face bright with a hearty smile.

I gave up on commenting. As long as Akari was happy, it was fine.

“Then I won’t hold back… Ah, yum… Mmm~!”

Akari cut a small piece of the chiffon cake with her fork and put it into her mouth, her body trembling with joy.

“This cake is so sweet and… delicious!”


Facing the sparkling light in Miyamae Akari’s eyes, Ruri Shiragi sat on the ground like a puppet with its strings cut.

“I was born into this world for this day…”

“Ruri, you are getting dirty like this.”

“Motomu! Don’t splash cold water on my mood! Of course, I will change into clean clothes!”

Although Ruri Shiragi got her uniform dirty due to being overly moved, a service industry taboo, the look of happiness on her back as she went to change clothes was unmistakable. After all, she was practically dancing her way there.

“Sorry, Akari. They told me yesterday that they wanted to treat you well since it’s a rare opportunity, so I agreed to their plan, but I didn’t expect them to pull these strange stunts.”

“Don’t say that! I am feeling incredibly happy right now! The coffee latte and the cake are super delicious!”

“That’s good to hear.”

“But, I feel it’s because you, senior, specially treated me, that I am able to enjoy these foods with such a happy heart. It feels like I’m dreaming…”

“Akari, you really have a way with words.”

Honestly, I don’t know what my contribution was this time. After all, I only took care of seating Akari and serving the coffee latte.

It seemed like Uncle and Ruri took all the credit… but I guess it doesn’t matter. Making Akari happy is what’s most important.

“I feel like I can study hard now.”

“That’s good. If you need anything, just ask me, don’t be shy.”

Akari said from now until closing time, she would be fulfilling her role as a student and study hard.

Even though I, who increase her burden by having her help with housework, don’t have the right to say this, I’m relieved that she can secure time for studying.

If she ends up with significantly worse grades after summer vacation despite being flawless now, that would be a serious issue…

“By the way, senior, how should we calculate the cost of this chiffon cake?”

“Well… let’s put it on my tab.”


“There’s no need for ‘buts.’ We already decided with rock-paper-scissors, right? And we never said we could only treat you to a coffee latte.”

Since the coffee latte was a special blend by Uncle, it might cost extra, but… if it’s extra, then so be it.

“Actually, we decided to put all your expenses here on Subaru’s account because it seemed fun. Whether it’s the coffee latte or the chiffon cake, every time you come to this shop to consume, his debt just keeps increasing… hehehe, I really want to see his reaction when he finds out about this.”

“Haha, if it really turns out like that, I could spend more time with senior!”

Hearing my joke, Akari also joined in with a brilliant smile.

That smile was so charming, I wanted to keep looking at it forever… but I couldn’t just keep staring at her.

After all, that would make her feel strange, and it’s still working hours.

“Then, I should probably get back to work.”

“Okay, thank you for the treat, senior!”

Akari put down her fork and placed her hands on her lap, bowing respectfully. It was very much in her style.


“What’s up?”

“Uh… just… keep up the good work!”

“Thank you, Akari.”

Akari’s face was as red as an apple, and she gave me a small smile.

Watching Akari put another piece of Ruri’s special chiffon cake into her mouth, I also got back to work spiritedly, not wanting her to see the embarrassing side of this store clerk.


“I’ve kept you waiting~!”


That night, the dinner Akari made for me was omurice.

The chicken fried rice was, of course, handmade by her, the omelet on top shone brightly, and it seemed even the French demi-glaze sauce on top was homemade.

In short, this omurice looked like something you’d find in a specialty store…! It’s amazing that she could prepare such a dish in a single man’s humble kitchen.

“Hehe, I might have tried a little too hard.”

Akari said this with a laugh, kneeling across the low table from me.

“Seeing you working hard yesterday, I thought all night about what I could do for you. I found a ‘Compact Supermarket’ on my way to the cafe, so I went there in the morning to buy some ingredients…”

“Compact Supermarket?”

“It’s a chain supermarket. However, this brand’s store is smaller than regular supermarkets… in simple terms, it’s an urban-type mini supermarket.”

“Ah… now that you mention it, I remember a supermarket like that opened recently…”

I remember it opening a month ago. Of course, I never shopped there, just passed by… but… it seems Akari is already more familiar with this town than I am.

“But, you already helped me with the housework, wasn’t it tough to go out and shop?”

“It wasn’t tough at all! As long as I followed the shopping plan, I could finish quickly. I even had time to prepare these sauces.”

“That’s impressive…”

“Hehe, not really.”

Akari shyly smiled a little. Although she’s modest, it must have been a challenging task.

At least I couldn’t do it. I don’t even know how difficult it is.

But I know what kind of girl Akari is.

She must have worked hard in preparation. She’s smart, but too honest.

These past few days have made it clear to me that she’s not the type to do things half-heartedly.

“I love omurice the most. So I’ve practiced it many times… I’m kind of confident in my skills.”

“That’s great…”

“Actually, I was planning to use this trump card for a more crucial moment, but since you said yesterday you wanted to know me better, so…”

Akari’s cheeks slightly reddened, showing a shy smile, looking incredibly cute… making me feel awkwardly shy as well.

Come to think of it, Akari has always been like this.

Until recently, she was just my friend’s sister, but ever since she came to live with me as collateral… her place in my heart has become increasingly significant.

If I get to know her better, what will our relationship become… Honestly, I can’t even imagine.

I’m not fearful… but this is the first time I’ve felt this way. It might be similar to being nervous.


“What is it?”

“I’ll work even harder. To make you appreciate me more, to become someone special to you, I must… no, I will definitely create a dish that surpasses this omurice in confidence – and one that you will love!”

Miyamae Akari blushed, declaring this with a slightly hurried pace, looking radiant. Then –

“I-I was just speaking off the cuff! The food is getting cold, let’s eat!”

“Okay, okay.”

Led by Akari, we put our hands together in thanks.

“Let’s eat.”

Thus, we began enjoying the omurice Akari put her all into making, but…

(What’s this feeling? I feel strangely unsettled.)

The omurice was delicious, a true delight. It seemed like I could eat any amount.

However, ever since hearing Akari’s declaration, an odd sensation began to stir within me.

My heart raced inexplicably, and my body felt slightly warm.

This was definitely not a negative emotion. It felt like a mix of happiness and embarrassment, yet it was different.

So, despite the delicious meal before me, my gaze couldn’t help but fix on Akari sitting across from me.

Enjoying her favorite dish, Akari ate with a blissful expression and an unguarded smile.

(I feel like a fool, worrying about such strange things.)

I didn’t know what to name this emotion, nor how to suppress it.

Even so, there was no need to panic.

While I might not understand this feeling yet, living with Akari over the next few days should gradually help me comprehend it.

I had a vague sense that, during these days and the process of slowly understanding Akari, this feeling inside me would grow stronger and more distinct.

Even though I didn’t know what this emotion was or how our relationship would evolve, I was very much looking forward to seeing the outcome.

“Senior, how is it…? Does the omurice suit your taste?”

“…Yes, it’s very delicious. Probably the best omurice I’ve ever had in my life.”

I nodded with a smile, and Akari’s face lit up with an even happier smile than before.

Although the relationship between my friend’s sister and a collateral still felt urgent and uneasy, words like “thanks” and “anxiety” couldn’t fully describe it, I found myself incredibly comfortable in it.

Therefore, I couldn’t help but think that I wanted to enjoy this peculiar relationship between a friend’s older brother and a friend’s collateral a bit longer.

“I’m here as the collateral for my brother’s debt. I will be in your care from now on” Miyamae Akari suddenly came barging in into Shiragi Motomu’s apartment. Giving off the impression of a good girl who cares for her brother, and a beautiful girl who would be gossiped about throughout the school, Akari suddenly offers herself as collateral for her brother’s loan. And that’s just for 500 yen. “Until my brother pays off his loan, I will gladly be your possession, senpai!” so she declared happily, for some reason. Motomu was bewildered by the overly wild development, but Akari pushily cajoles him and steadily goes forward with the preparation to freeload. And of course, this whole “collateral” thing has another motive――. It’s the start of a single-room cohabitation with a beautiful proactive girl!
