Dr. Yeoh-jin tells the gang that he's going to have to see Kim-yangseob. He's worried about the girl's health and wants to make sure she's okay. He tells them to keep the whole thing a secret from her parents. He says he'll be back in a week or so to collect more blood from the girl. He doesn't want to be a doctor, he says, and he'd rather be a "cunning nymphomaniac" than a doctor. The doctor says he hasn't seen Kim in a few days, but he still wants to call him when he does. He also says he saw a strange man in the hospital a few weeks ago, so he wants to find Kim as soon as he can. He has a patient who has a rare blood type, which means he needs to figure out who Kim is before he can perform the surgery. He decides to report Kim to the surgeon immediately, since it's such a consult case. He wonders if he should drop his doctor's responsibilities and perform the organ-resection himself.
