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

“This is bad. It’s really bad, Onii-san!”

　The time has passed a little and I’m cleaning the bathroom. As I was cleaning the dirt from the bathtub with detergent, a frustrated voice came from behind me.

　I didn’t need to check who the voice was. It’s just me and Shiori-chan in the house right now.

　I stopped holding the sponge and turned my head.

“What’s wrong?”

“I think I have a disease that will kill me if I’m not around Onii-san!”

“Too strange…”

“So, I’ll help you clean the bathroom.”

　Shiori-chan clasped her hands tightly and showed her motivation with sparkling eyes.

　It’s nice of you to help me with the cleaning, but it’s my role to do the housework (except for the laundry).

“Don’t worry. It’s my job.”

“But if I don’t stay with Onii-san, I’ll die. Are you okay with that?”

“You won’t die, so don’t worry. More importantly, why don’t you do your homework for the summer vacation? You still have some left, right?”

“Ugh… Onii-san is a devil for reminding me about my homework. But I love that kind of Onii-san too!”

“Oh, thank you. But I’m not trying to be devilish, you know. If you put off your homework, it’ll be hard to do it all at once later, right?”

“That’s right…”

　You’re really coming on strong, Shiori-chan.

　I know that it’s quite difficult to say that you like me, but Shiori-chan is trying to convey all of her affection for me.

　To be honest, I don’t feel bad, and I’m honestly happy. But on the other hand, I also feel embarrassed.

　Also, I feel bad that I haven’t been able to respond to Shiori-chan’s “I love you” feelings.

“Homework… Homework huh… I don’t want to do it… but Onii-san won’t do it for me… Haa~.”

　Shiori-chan muttered in a muffled voice and turned on her heel. Her breath was heavy and sinking.

　I scratched my cheek with my finger and called out to Shiori-chan’s back.

“You know.”

“…Yes, Onii-san! What is it?”

　She turned around and gave me a lively smile.

　I was a little reluctant to say anything, but I decided to start.

　Shiori-chan is telling me that she likes me without hiding it. It’s not sincere enough to just accept it.

　So, I should immediately rethink Shiori-chan as a person of the opposite sex and face her feelings.

　To that end,

“When I finish cleaning the bathroom, do you want to go out somewhere?”

“Eh, yes, by all means!”

　Shiori-chan’s eyes swam for a moment, as if she didn’t expect me to ask her out.

　A faint blush crept into her cheeks and she leaned forward, lowering her head vertically. 

“In return, I want you to do your homework for me, okay?”

“Yes, of course! …A date. Yay, I can have a date with Onii-san. Yipee, yay!”

　Shiori-chan made a small gut pose and jumped up and down on the spot with a happy face.

“Are you that happy?”

“I’m so happy. I can’t tell you how many times I’ve fantasized about going on a date with Onii-san… I’m deeply moved to think that it’s finally going to happen.”

“You’ve been fantasizing about it…”

“Of course I have. I’ve lost count of the number of times Onii-san has taken care of me on sleepless nights… I’ve been to amusement parks, climbed observation decks, gone to fancy restaurants, and─”

“You don’t have to dig too deep into that story.”

　Shiori-chan snapped her fingers and started talking about her fantasies.

　Everyone has one or two fantasies, but it’s awkward to be told about them directly. Especially when I’m in the middle of it.

　Shiori-chan’s dignity would be at stake, and it would be better not to dig too deep.

“I’ll go get ready for our date!”

“Ah, Oh… You don’t have to be so uptight about it, okay? If we don’t have the time, you don’t have to go that far… Ah, she’s already gone.”

　I was a little puzzled by the unexpectedly delighted look.

　The fact that she has been aware of me since she was in first grade does not seem to be an exaggeration.

　I strengthened my grip on the sponge and finished the rest of the bath cleaning.
