Why you should watch this drama and actually enjoy it?? For the SM idols of course. Other than that, the drama is just, well, boring. To be honest, I'm still trying to finish it, while picking up It's okay its love (note, SM idol again plays in it). However the story does not appeal to me, so it's hard to keep watching it after the third episode. Honestly, I'm not a big fan of any of the idol groups of SM, and I didn't really recognise any of them easily, so, for me, this drama is just like any others. The story sounds okay, though the first episode doesn't really explain why the girl chose to dress up as a boy and attend the school. It was hinted that she may have a crush on the lead actor, but she actually hasn't, as it is revealed through the next episodes. She just admires him and wants to help him. Her acting though isn't that good, and the situations where she almost has her identity revealed, which should have been funny and awkward, are just bad. To top that, the romance is bleak, with the two actors showing no attraction for one another. Maybe the only thing that kept me going was actor Hyun-woo Lee, who's one of my favourites, though he even couldn't save this drama. So 2 out of 10. PS for all those of you who want to watch the drama for EXO, they appear for probably ten seconds in the second episode, so don't even bother.
