I actually had to stop watching this. My problems are:

- Not an amazing OST
- Acting was so-so
- Storyline is clever idea, but pretty bland

My main problem:
Both male love interests are not nice people. The main treats her awfully at the beginning and even after he starts to warm to her, he ends up being mean just because he feels like he should hate her? Because he feels like he's betraying the fake Hye Jin? Like, what?

And when he thinks she's not interested in him romantically, he starts to act distant and really horrible. Like, just because she said no to being romantically interested, that gives him a reason to act like he doesn't care anymore? That childhood friendship doesn't mean much to you once you find out you're not going to be her boyfriend, does it?

The main male character has a boring personality, nothing stands out, he's just so bland.

The second male character is a little better. He's charming, nice, funny, plays tricks on Hye Jin, listens to her, helps with her problems. But then when she turns him down, he starts ignoring her, acting miserable around her, deserts her. Tells her he can't be her friend.

Both love interests are despicable people, and I really don't have an interest in watching this strong female lead get pushed around just because she says she's not interested.

The one saving grace of this drama is the friendship between Ha Ri and Hye Jin, they would be the only reason I keep watching. They have a strong friendship and so much trust.

Hye Jin girl, ditch the two trash men and be with Ha Ri, in my opinion.
