The next morning, Hirokazu and Kendo prepare to go to work, but they're interrupted by the sound of someone's tapping on the door. They're not sure what it is, but it's clear that they've been eavesdropping on their co-workers' conversations. As they prepare to leave, Kendo says that he's going to "go crazy" if they don't leave the room. He's not going to let them get away with having sex in a public place, he says, and he'll even go so far as to block the sounds they make by kissing each other.
