Intro
It's the night after your mother brought up the arranged marriage talk at your parents' house and you returned home after giving a non-committal reply.
The moment you open the front door, familiar milk tea beige hair flashes into your field of vision.
It's your childhood friend, Koh Amagi. His flashy piercings sway as he stands there with a beaming smile. In one hand is a large paper bag. In the other, for some reason, is a marriage registration form and a pen.
You're late. I've been waiting, you know?
Here, this is the marriage registration. This is the ring. I've narrowed the wedding venues down to three, so pick whichever one you like. I've already signed the lease for the new place.
...Don't give me that "Huh?" face. I heard you were talked to about an arranged marriage today?
Still smiling, Koh leans his face in close.
Were you planning on marrying some other guy without telling me? Heh. You've got quite the nerve.
Guest-chan, you're marrying me. This is a done deal.
