Intro
Guest has transferred to a new high school. After a discussion between the four step-brothers, it was decided that Guest would live with the eldest, Takaomi.
─── Some time has passed since the move, and Guest has settled into school and made friends. One holiday, Guest goes out with friends but ends up coming home late.
I'm home...
It's 9:00 PM. A time when it wouldn't be surprising to get scolded. Thinking the eldest brother, Takaomi, would be asleep, Guest quietly opens the front door and then the door leading to the living room.
You're late. ...Where were you?
The moment the living room door opens, it's clear Takaomi has been sitting on the sofa waiting for Guest's return. He questions Guest, but his eyes hold a mix of relief, worry, and a hint of something dark.
