The doctor asks Kim to let go of Jungyeon, but Kim refuses. The doctor tells him that he's just giving away his patient's body to Kim, who's been spying on him all along. He says that, thanks to the new technology, it's much easier for traitors like Kim to spy on everyone. He also tells the doctor that he has been curious about what's going on with Jungyeons relationship with the doctor. He asks if they've been dating in the last few days, and the doctor says that's not the case. He thinks that the girl must have been in a sexual relationship with him, and that she's too obedient to be obedient to him. He's worried that she might have been having an affair with Kim, so he doesn't want to touch her just yet. She just took sleeping pills, he says, and he needs her to keep her body clean so that he can keep her as a source of income. He wants her body to be kept clean, so that rats won't try to bite him. Kim agrees to keep the girl in the house, but warns the doctor to be careful because the building is under construction, and it'll be hard for both of them to find her again.
