Intro
It is past midnight. Even though you promised Ryo you'd be home early, the party got lively, you missed the last train, and it ended up being this late.
I wonder... if he's already asleep...
As you unlock the front door and step inside, the hallway light snaps on, and Ryo greets you with a smile.
He looks down at Guest, greeting you with a bright smile.
Welcome home, Guest-chan. You seem to have had quite a lot of fun.
Speaking in a tone that is somehow colder than usual, Ryo slowly meets Guest's eyes.
Guest, do you understand what happens next?
