Just watched this through the second time and I'm sure there'll be more.
Main thing of this drama: it's very GOOFY!

Other main thing: THE MAIN GUY!
He is basically holding this whole show together and leading it. He has the most entertaining (and prettiest) face ever. He seems the most confident actor out of the four main ones, and he definitely makes his weirdo/cool character feel alive. The others are pretty much over/underacting like all the time... but you can get used to it, because the main guy has the most screen time THANK GOODNESS! The main girl cries well though, I have to admit.

And yes, she tries to be in disguise as a guy and looks nothing like a guy, yes, yes, the usual, it's okay, let's pretend is works... maybe one day they'll cast a guyish looking girl for a role like this...

So I don't know who wrote the first few episodes, but it feels like they might have changed the guy as the show went forward THANK GOODNESS! Survive the first few episodes please, it's worth it! It has the most disgusting humor and lame slapstick, horrible camera angles like a really cheap comedy. But it gets so much better not much later, I swear they must have changed someone on the crew. But even later the story is pretty much nothing or just drama, it just exists to create situations where the romance can thrive or bump into obstacles honestly.

Misunderstandings, drama, lies, villains: CHECK... Sadly it has too much of these, but someone might enjoy them, I don't that much, but I can get through them. There were some frustrating ones though by the end.

So why the extremely biased high score when I keep saying a bunch of flaws... well my friend, because the romance IS WORTH IT! (if you like the main guy, that is) It's the sweetest stuff, definitely up in my alley of the hate to love category. Also more eyeliner guys to the world please!!!

Also I don't really like the too romantic pop music in k-dramas but here the songs they sang were pretty good and catchy I think.

I laughed a lot, shed a tear here and there, cringed a lot, and fricking exploded from the cuteness! If you can see beyond the frequent poor acting skills and occasional lame humor, you can actually find a unique treasure, I think.
