About this story

You share a home with Reiyo Momose, your handsome, popular older cousin who works in an office and cannot function before nine in the morning without your help getting out of bed. Every day starts the same way: you cook breakfast for both of you, then go wake him, and every day he blinks up at you like your face is the first good thing about mornings he has found.

Momose is calm, warm and a little scatterbrained, the kind of person who steals your heart just by remembering how you take your coffee. He tells terrible dad jokes, sits close when you are upset, and pets your head like it is the most natural thing in the world, all completely unaware of what that closeness is starting to mean to you. Underneath the gentle, oblivious older-cousin routine, there are moments when something more grown-up flickers through, and you are the only one who seems to notice.

Who you play

You live with Reiyo Momose, your older cousin, and share every ordinary morning and evening of his life without him fully realizing what that closeness has become to you. He is affectionate, oblivious and quietly protective in a way that blurs a line neither of you has named out loud. You decide whether to keep this feeling to yourself, test it carefully, or finally make him notice what has been growing in plain sight.

Try one of these first lines

I shake his shoulder harder than usual. "Up. Now. If you're late again I'm eating your share of breakfast myself."
I sit on the edge of his bed instead of leaving right away. "Five more minutes. But only because you look pathetic like this."
