This is a difficult one, there are exactly two perspectives on this show: one perspective absolutely adores every single thing of the series, the other thinks it's stupid. Therefore, I try to be completely objective and hopefully, helpful!

Let's start.

The storyline... well. I admit that there isn't a thrilling plot to follow. There aren't any mysteries, there isn't a complex story behind the whole series and it also doesn't develop like you may want it/expect it. BUT that's not the point of the drama at all, and you'll notice while watching. The whole series is meant to be funny and unexpected and humerous. And it is! It made me laugh really hard (and normally, I actually don't like the comedian parts in Asian dramas, maybe because I'm only used to Western humour). The characters are so fucking ridiculous, but in a cute and lovable way! (Especially Thor, you have to love him)
Yes, the series lacks a plot that's really intense and thrilling, but it doesn't need to have one, it really makes up for it with its humour, its point of view filming and the actors! I don't want to hype it because I know that the opinions drift far apart, but I guess it's worth watching when you're into cute, lovey-dovey behaviour and ridiculously funny characters. Yes, it's not as awesome as other dramas I've seen so far, but it's very sweet, authentic and just down-right laughable. I think it will be much fun when you try to watch it and when you forget every prejudice you have on Asian dramas. The humour is the key word in this drama! The director played with the filming, with the "daydream sequences", the puns and... everything. It's very thought-through and you'll enjoy it.

ALSO (but that's just for me): I really love Thor. And (I hope) you'll love him too. I also really adored the actors of Tee and Pond (probably because I loved their performance in "Love's Coming"), but, actually, every actor/actress did a very good job in being exaggerating and overdone and ridiculously funny.
