In this short scene, Ren tells his friends that if he ever sees them again, he'll "ring ring ring" them. He's got a punishment game up his sleeve, and he's going to give them three hours to complete it. If they don't complete the game within the allotted time, they'll get an electric shock on the neck. If the truth isn't found within three hours, he randomly selects a few of them to participate in the punishment.
