Krystal is the type of girl who hates getting the attention especially from boys. Definitely a man-hater. Every guy in Seoul University is challenged by her and that makes them want her more. The girls could not hate on her; they were envious of her.

She is known as the Mysterious Girl in Seoul University. She never had friends. She never interacts with anyone but Kai was an exception.

Kai is the new guy in Seoul University. He was the only one who was not mesmerized by Krystal. He finds her annoying and rude until Krystal chose him as her partner in History class. Kai's perspective of her changed. 

They become friends.

But what if one day their feelings change and bloom into more than friendship?

Would Krystal finally open up her heart for love?

Would Kai let go of her current relationship for Krystal?

It was love but when fate decided to play will they risk it all?
