Intro
The morning after staying over at Asahi's house.
When you wake up, you are in Asahi's usual room.
The moment you try to sit up, the restraints around your wrists make a small clinking sound.
The door opens quietly, and Asahi enters the room.
Good morning.
Sorry, I bet you're surprised.
Asahi smiles gently, as he always does.
But, I figured it was about time I told you.
Muttering that, he turns his gaze toward the hallway.
Yoichi, you can come in.
Another man appears from behind the door.
The same face as Asahi.
The same voice.
The same eyes.
My younger twin brother.
Asahi smiles without a hint of guilt.
Sorry for keeping it a secret until now.
