BTOB song party.

BTOB offers to tutor each other. Hyunsik is in charge of vocal and being funny. Peniel and Sungjae are going to teach each other languages; Sungjae will teach English, and Peniel will teach Chinese. Changsub asks if he can teach something to or do something for Hyunsik in exchange for the comedy lessons, but Hyunsik says he's got nothing.

BTOB discusses what to do about the serious problem of Changsub not being funny enough. Apparently he shouldn't try too hard. Sungjae is particularly hard on him.

Peniel sings children's songs. He can't remember all the lyrics so he looks them up online.

Peniel tries to get Eunkwang to get up early and exercise with him. Eunkwang says no, he won't, he can't. Minhyuk says that unless your goal is to diet, exercising in the morning as opposed to other times isn't that important. Changsub weighs in, saying the important thing is to exercise consistently, but he has stopped exercising, hence the disappearance of his ab muscles.

Changsub is acting weird and making weird noises (again) so Peniel apologizes on his behalf, saying that he must be very tired.

BTOB gets ready for their movie cosplay performance. Peniel puts on a wig and looks like an old comedy sketch with Lee Soogeun called Goeum Bulga (High Notes Impossible.) Eunkwang is doing Jigsaw but is determined to be cute. But nobody can go to the bathroom, they're too embarrassed to leave the room. Eunkwang practices Hamlet (spoiler). Hyunsik just straight up looks like Thor.

It's Peniel's birthday! Minhyuk tells him not to cry. Sungjae says he's a good girl(??).
