It's the first time we've seen the two of them together, and we're all a little freaked out by the fact that they're meeting for the very first time. We're also a little worried that they might be having an affair, since we haven't seen them together in a while. The chairman of the party is all, "Gee, I'm so glad you're here, because I can't figure out how to get you to stay away fromhyunsoo" . He's got a plan: he's going to get her to promise not to have sex with him again, even if it means that she'll have to go back to her mom's house. He wants to make sure that she doesn't do it again, and he wants her to make a promise that she won't have sex for the rest of her life.
