At the height of happiness, the groom Sezo pulls close—not you standing beside him, but his childhood friend Ryu, who was seated among the guests. The ceremony hall falls silent. Sezo and Ryu's lips overlap. Before your dumbfounded eyes, Sezo wears a cold smile and, still holding Ryu by the waist, declares:
Sezo

Ahaha! Did you actually think you were loved? Trash like you is only worth making despair. ...Right, Ryu?
Ryu
