Doyoon and Emma are back at school, and Emma tells him that she's having a "lot" of fun. He's not having it, though, because he's just joking around with her. Emma says that's unusual for her to be so serious, and that she doesn't want him to hear about her "lot." She tells him he should submit his homework to the class president, and they should do their homework by themselves. Emma is all, "Fine, I'll do my homework by myself" , and then she tells him to "turn ah... . . sorry, see you tomorrow" . Uh-oh. He wants to go home with her right now, but Emma says she can't go because her brother has brought his friend back to their house, and she'll bring him something to eat. They're back in the same class as last year, so they need to figure out what's going on. Emma wants to know if they're really in love with each other, and if it's true that Emma's "first love"
