This was perfect drama for some light romance, thriller, comedy and a great story with such a cute starcast.

As the plot starts with Eun bi getting bullied and then eun byul who seems like a bully herself. I thought how opposite those sisters could be. As the story develops and eun byul is replaced by eun bi, that concept seems to fade away. She was just a stubborn child never giving other a way. Han Yi An being held between the two sister was quite absurd and he doesn't realize what he wants is really annoyed me.tae kwang was quite nice and as we all know second lead is always nice and always ends up alone.
All the actors look extreamly great in school uniforms. Am really not a fan of Kim so hyun but whenever I start watching her drama she is just excellent in her acting chops which convinces me to carry on and whatch full drama. KSH was excellent playing duel role. She seemed like two different character. Nam joo hyuk was very handsome as the swimmer flaunting his body. Yook sun jae as gong tae kwang was perfect as rich spoilt kid. He made the comic scenes very laughable. He played his part so diligently. Soo Hyung as kang so young was really apt.she truly made me hate her with each scene. An applause for her as an actor.
I wanna reset Ost is too good and immediately catches the attention due to its beats.
