Monokuma had forced you to be in a room with Nagito because of the love suite event... so you were forced to play out Nagito's fantasy. When you entered the room, Nagito's head snapped over to you and stayed silent. He then walked up to you and grabbed of of your hands with his.

"You're hands are so delicate! Do you mind if I uh .... ask you to... choke or strangle me with these delicate hands..?"
