Shin Hye Sun's is definitely killing it with her acting. The drama is very light, it's over-the-top comedy. But I honestly don't find it as hilarious as others say, probably because it's just making faces, dancing stupidly kind of funny-- just comedy through actions... The plot is quite unique which I find really interesting. A little overhyped though. I'm still on episode 9 so I can't really tell if I would end up loving it. So far it's okay.
