For Some Reason, My Little Sister’s Friend, Who Is Totally Devoted To Me

“I think we need to set some rules.”

　After we finished washing the dishes, Shiori-chan and I sat across the table from each other.

　As I propped myself up on both elbows and rubbed my hands together, Shiori-chan tilted her head and ruminated on my words.

“Rules, you say?”

“Yeah. Five more days. Including today, it will be just me and Shiori-chan living together for six days. So I thought we should have some rules about living together.”

　Shiori-chan put her hand on her chin and nodded her head.

“I see. That’s true. But before that, can I make a correction?”

“Eh? Yes, yes, but what correction?”

“It’s not living together. It’s cohabitation, Onii-san.”

“No, it’s living together. Cohabitation changes the meaning. To be more precise, Shiori-chan is now a housemate.”

　When you say living together, you’re talking about a man and a woman in a relationship. The relationship between me and Shiori-chan is not that of a man and a woman, or even friends.

　A little sister’s brother and a little sister’s friend. When you put “little sister’s” as a pillow word, you can’t call it cohabitation.

　However, Shiori-chan puffed out her cheeks in frustration, and her eyes widened halfway and she let out a breath.

“I don’t like the sound of that… I want to live with you. Please, Onii-san, let me go from being a housemate.”

“If you don’t like being a housemate so much… why don’t you just go back to your parents’ house?”

“…Well, if you insist, I don’t mind being your housemate for now. I’m sure we’ll be together eventually, Onii-san.”

　Shiori-chan smiled at me.

　My heart skipped a beat and I gently turned my gaze away, my cheeks blushing. Isn’t this already a confession?　

　Shiori-chan, who doesn’t seem to hide her affection at all, continues to surprise me.

　She was a friend of Yuzu’s, and I only recognized her as a cute girl, so I didn’t expect her to be so aggressive.

　Let’s calm down. Let me calm down for a moment.

　I’m going to be a dull character like the main character in a romantic comedy.

　I’m not aware of Shiori-chan’s affection. I’m not going to be able to keep my wits about me if I don’t set it up that way.

“Let’s get back to the topic at hand. The rules for living together… that’s right. So, let’s decide on the division of household chores.”

　When I started the conversation, Shiori-chan raised her hand and declared, “Yes, yes.”

“I’ll do all the housework and cooking. After all, I’m the one who’s staying at your house. So please, let me do it!”

“Eh? That’s not going to happen. We have to share the work properly.”

“Onii-san works part-time to earn money, doesn’t he? It’s not easy to work outside of the house and work at home too. Please let me take care of the house.”

“It’s nice of you to say so, but the part-time job is self-supporting and all the money goes into my pocket, okay? You don’t have to worry about it.”

“Onii-san will definitely be a good husband in the future if he doesn’t neglect his family.

“Eh, o-oh… thank you.”

　What should I do? I feel like I’ve raised my favorability. I just said the obvious, but…

　Shiori-chan’s eyes sparkled with an enraptured expression.

　I smiled awkwardly, held up my index finger, and cut her off.

“Okay, so Shiori-chan will do the cooking and I’ll do the housework, right?”

　I know that Shiori-chan is a good cook, as of yesterday. Since that’s the case, I should leave the cooking to her, then.

　I mean, after eating Shiori-chan’s cooking, if I cook, the disparity in taste will be so great that it will break my heart.

“I don’t mind if Onii-san is okay with it.”

“Then it’s settled.”

“Okay. So Onii-san is going to see my underwear… But rules are rules, right? It’s embarrassing, but I have to put up with it~.”

“I’ll make a correction. Let’s do our own laundry.”

“Eh, no, it’s a waste! You’ll save money if you wash it all at once. Let’s do it together!”

“No, but..”

“Do you and Yuzu-chan do your laundry separately? If so, it’s a different story.”

“No, I don’t, but…”

　But Yuzu is my little sister. Of course, I don’t have any ill feelings towards her. Whether it’s a pair of pants or a bra, it’s just a piece of cloth. I don’t lust for them at all.

　But when it comes to Shiori-chan’s, the story changes. It’s not a problem that can be solved together.

“Anyway, let’s separate the laundry. You don’t want your father’s clothes to be washed with yours, do you?”

“I don’t like that, but that’s not the same thing.”

“…But still…”

“I’ll do the laundry. That won’t be a problem, will it, Onii-san?”

　She suggested with a soft smile.

　It’s true, though, there’s no damage done when she sees my pants.

“You don’t mind, do you? Even though they’ve been washed, it’s not something you want to touch too much.”

“Eh, it’s a rewa─*Cough, don’t worry about it. I’ll be just fine. You’re very considerate, Onii-san.”

　Shiori-chan clears her throat deliberately, and then says, “You’re very considerate, Onii-san.” I thought she was about to say something unpleasant, but I’ll just pretend that I didn’t hear it at all.

“So, I’ll do the laundry. I’ll be in charge of the laundry and cooking, and Onii-san will be in charge of the rest of the housework.”

“Ah, yes. That’s about it.”

　As I was told, I nodded my head. Shiori-chan smiled brightly at me.

　She took out her cell phone and held it out in front of me.

“In case of an emergency, you can’t contact me, right? Why don’t we exchange contact information, Onii-san?”

“Yes, we should.”

“And be sure to keep in touch with each other. If you’re going to be home late for a part-time job, please report it to me. I’m quite a worrier.”

“O-Oh, okay.”

“Also, please consult with me about anything. I’ll help you out.”

“Yeah.”

“Well, that’s the rules for now, and if anything happens in the future, we’ll add to them as needed.”

“O-K!”

　…Hmm, huh?　

　I don’t know when I lost the initiative. Well, it doesn’t matter.

　I was relieved to know that the rules for living together were set in place, and Shiori-chan smiled and leaned forward to put her face close to mine.

“Oh, that reminds me, Onii-san, there is something I want to tell you.”

“Hmm, what is it?”

　Shiori-chan looked into my eyes.

　She stared at me with her wide, piercing eyes.

“…I like you, Onii-san.”

　Shiori-chan clasped both of her hands together as if she were wrapping them around me, and suddenly told me that she liked me in a way that was too direct.
