My best friend fell in love with me, but I didn't feel the same way. I said things about him that I shouldn't have, I pushed him away without even knowing. He left without saying goodbye. That's when I realize how much I love him. Am I too late?

Jiyeon has been in love with senior student, Yoo Seungho. He knows but he ignores her but Jiyeon would do anything to get close with him. Unfortunately, she heard him say he doesn't like her and the worse thing is...He likes Jiyeon's best friend, Kim Moon Joo. Will Jiyeon easily give up and will Seungho realize he actually likes Jiyeon the way she does to him?
