This is a review from a non EXO fan. There are two sides of this drama: first, EXO, and the fans and second, FRIENDSHIP. A must watch? YES, for all EXO fans, KPOP fans, fangirls and even Korean Drama fans. It is something which every episode will give you warm heart vibes. Plus the dialogues, the casts, EXO members, Moon Ga Young and others.... I love them. Simple but SWEET. If you're looking for something to watch which will made you feel so relax, this one is for you.
