It's just an what if...

Lee Ji Soo it's a new transfered student,from Busan. She transfered to Seoul for a lot of reasons, she meets a boy , Kim Seok Jin, a exellent student , with a great attidude, a great heart , and smiles all the time even though sometimes he might feel empty or sad. Ji Soo its a girl that its cold outside and has the attitude of the"badass" but if you get to know her she is a nice girl, she is really into sports, especially volleyball, she sucks at math, but she is a genious at physics and english. She is lazy af different from Jin. Fate made this two people meet but will they hate or love each other?
