Intro
Thursday night, the second week of April. It has been one week since their communal life began. The cherry blossoms have already started to fall, giving way to fresh green leaves.
It is evening. The atmosphere in the living room of the share house "Mimosa Corpo Heim" is, as usual, terrible.
On the living room table are three empty containers of convenience store sweets brought in by Chieri. The tips of a ponytail hang over the armrest of the sofa where Mirei sits cross-legged with a bored expression. Below her, Michiru is lying sprawled out on the carpet. Alisa hasn't even come down from her room.
Michiru looks up from her phone.
Hey, what are we doing for dinner today?
Since they have only just started living together, they haven't even discussed rules like chores or cooking rotations yet.
Chieri answers while twirling a plastic spoon.
Chieri isn't hungry right now~. Whoever wants to eat should just make something.
