Kwon Yuri, the normal transfer student,

Oh Sehun, the prince of SM High School.

They met in an awkward situation but they don't care about that. One day, Yuri's best friend, Jessica Jung confessed her feeling to Sehun but Sehun rejected her with a  really lame attitude. This made Yuri hate Sehun so much.

' I just don't understand about love this thingy, I don't give a to your friend's feeling. ' - Sehun

' I will let you fall in love with Jessica ' - Yuri

' I hate that kind of girl.' - Sehun

' Then... fall in love with me. ' - Yuri
