First of all, I'd like to say that I'm crazy about Jo Jung Suk, so if you're a big fan of him go watch this right now >>>> you'll get to see him express all kinds of emotions in these 24 episodes, that you'll end up in love with him even more.

The story:
I read a review that said the story is messy but perfect kind of messy. I didn't understand this until I started watching this drama... I ended up finding it the perfect description for it.
There is a lot of side characters (which I usually hate) but for this drama, I loved each and every one of them.
The beginning is a bit slow but after a few episodes, you'll find yourself hooked to know what will happen next.
The romance is perfect. If you're a romance fan you'll be satisfied. I think this is the best love triangle of all the dramas I've seen.
The comedy... God the comedy was amazing, beyond perfect actually, I was laughing all the way from the 1st episode till the last moment (which doesn't happen easily)
It was so refreshing and new., I'll definitely remember it for a long time.

What I didn't like :
- There was no actual plot. It felt like I'm just living their daily Lives with them. It wasn't bad but it could've been better.
- Towards the end they gave up on some of the side stories, it bothered me a little but I got over it because there was a lot happening with the main story.
- They could've finished it in 20 ep (not 16 though) it would have been richer with events.

The acting was perfect. It was like Every actor was made for his character.
Jo Jung Suk is at his best. I fell in love with him all over again..he was perfect for this role and I don't think that there was someone who could do it as well as he did.

The music was wonderful. A big part of the drama was the music. It controlled your emotions during different scenes.
Without the music, it would have been a very sad drama so thank God.

Overall I strongly suggest you watch this if you don't mind the simple plot and a fan of romantic comedy.
