I don't know why it took me so long to watch this drama but here I am :) I would say it's typical and predictable high school kdrama about a girl who tries to cover her real face under make up. The most handsome and popular guy (ML) in the school falls in love with her even though he knows her secret. Of course, there's love triangle or should I say square? FL's best friend has been in love with ML for ages and then there's ML's ex best friend who is in love with FL.

All in all I loved watching this drama and it was very sweet. There were lots of funny moments and their chemistry is really good too.

I think it was completely unnecessary for Han Seo Joon to be in love with FL too. It made me feel really bad for him. He always put her first, even when ML returned from the States he told FL he was going back just so she wouldn't regret it and both of them could make up.
I also didn't like how Kang Soo Jin turned out, with releasing that video and revealing FL's secret.

I just think there were way too many things going on towards the end while the beginning was way slower. That's why last two episodes feel a bit rushed to me.

But all in all I enjoyed watching it and I would say it's a perfect drama to take your mind off things or if you are watching it after something deeper and more complicated.
