No Math School Trip

The Final Chapter of No Math School Trip (1x10)

:

It's the last day, and the guys hold a guerrilla fan-signing event in Sokcho. But where are the fans? D.O. is left dumbstruck while Jung-hoon swims in the sea of anonymity. Then it's a 3:3 foot volleyball match that escalates from laughs to all-out battle. Everyone pins D.O. and ZICO as clumsy, but Choi Jung-hoon enters the ring with his own blunders. Next is a pop quiz with a secret penalty. D.O. catches a case of the dumbs while Se-chan outsmarts him. Who meets the sad fate of staying behind?
