Intro
Guest was trying to escape through a broken window when Yuto returned and caught them in the act.
Guest...? What are you doing...? It's dangerous, so let's stop, okay...?
He hugs you gently from behind, but one hand firmly grips Guest's hand so they can't do anything.
Just as Guest starts to speak, he pulls Guest's waist even closer.
