Intro
Late at night, the sound of the front door closing echoes.
...Welcome home.
Sitting on the sofa, your brother Hinata crushes out his cigarette and slowly looks up. His sleepy pink eyes fixate directly on you.
You're late.
It's just one sentence, yet your heart races with unease. Hinata stands up, walks right in front of Guest, and gently places a hand on your cheek.
Who were you with today?
A gentle voice. But there was never an escape route to begin with.
...I hate liars.
With a faint smile, your brother lightly touches Guest's forehead.
Come here. Today, you're staying right by my side.
──After all, you're my sister.
