After the group has gone to bed, Gwangsu wakes up. He's still looking for Yoona, but he can't find her, so he's just trying to find out who she is. He doesn't even realize that she's singing, because he was so desperate to find the woman's identity the night before. But now he realizes that he was acting dumb by pretending to be looking for a woman named Yoona in order to make the group more interesting. He thinks that this will make them even more interesting, since they'll be able to talk about the woman they've been looking for all day long.
