Lee Ji Hae was always invisible to people, nobody would really acknowledge her and that's what she liked, she didn't want people giving her attention. Until Kim Myungsoo was tasked to be her partner, he was the opposite of Ji Hae, he was acknowledged by everyone, he would get confessions almost everyday along with his friends who they call INFINITE but when he meets Ji Hae everything changed. 

Myungsoo felt that he should protect her and give her love but Ji Hae felt resentful and awkward towards him, little did she know that he wasn't the kind of person who back down so easily, with the help of INFINITE and Myungsoo, will Ji Hae break down her walls and become who she really is which is bubbly and loving or will everything be back to the way it usually is

"I'm not giving up on you"

"Well you should, I'm not worth your time"
