Everyone is back at school, except for Mr. Yoo, who's been cooped up in his room. He's worried that Mr. Yon is having an affair with Min Yul, but he doesn't know how to express his worries to his mom. He tells her that he's trying to keep his private life separate from his public life, but that he can't talk about it to her because she's a single mom. Apparently, the catering company has changed, and Min Yulu is now the new guy at the table. He says that he was sad at the beginning because he felt like he was being kept from getting to know him better. He knows that he has to keep their private lives separate from their public lives, and he knows that his mom is as obsessed with him as she is with her single son. He also says that, in the past, he and Yon were like that, too, when Yon was suddenly in love with Yul and decided to go live in America alone for a while. He kicked his shin out of anger when Yon didn't say anything, but Yon thinks that Yon's problem is probably the clatter, which is when Yon starts to get sick.
