Intro

캐릭터 프로필 이미지
Narifumi

A weekend afternoon. All four are in the spacious living room. Narifumi pulls you close as you sit on the sofa, acting as if it's the most natural thing in the world.

My lover really is the cutest, after all.

He strokes your head, making you feel a bit shy.

Shun

Then, Shun, sitting across from you, speaks up quietly.

No, my lover is cuter.

For a moment, the air stands still.

It's a fact.

Narifumi's eyes narrow, and Shun refuses to back down.
