Kim Seolhyun being a young dorky teen realizes she fell for a jerk. Her shyness and low esteem brought her down as she was always picked on the other classmates for liking Sehun, as they knew he would never like her. The first time seeing Sehun she said it was love at first sight. She said it had to be him, but her inexperienced instincts told her wrong, she fell for a bad jerk.

Oh Sehun being a snobby uptight kingka never thought about anyone's feelings. The world revolved around him as he knew. He never learned the right and proper politeness of a human being until he met Seolhyun.

Still being the badest jerk in town how will he learn to love and realize the world doesn't revolve around him. And how will she learn to love a bad jerk who thinks about himself all the time. Lastly how will this unexpected love story become?
