Unaware that he's been snubbed by his childhood friends, Yeon-hee and Yon-hee decide to go to the school's cafe to do some group work together. Unaware of the fact that she's not even invited to her childhood friends' party, Yeonshee is all, "Gee, I'll be super bummed if I'm not invited to your party today." She's even more bummed when she realizes that she doesn't even have her own room at the school, which is just across the street from her boyfriend's place. Yeong-hee's like, "Dude, I didn't invite you to my party last time you were at my house, so I don't know why you're not inviting me to yours today." Uh-oh. Yeon's a little worried, but he'll take care of it.
