Chu Sang Woo is a computer science student who prizes reason, rules, and a rigid sense of what is right above all else. As part of his university work he needs to work on a group project for the liberal arts, where the group is required to make a final presentation in order to pass. But as the rest of the group decided to leave all the work to him, he decides to remove their names, and make the presentation in his name. But little did he know he would deal a heavy blow to the academic prospects of a senior student named Jang Jae Young, a design major and Chu Sang Woo’s polar opposite. He is stylish, fun-loving, and – above all – extraordinarily popular. But when his credit for the liberal arts project is taken away, his grand plans to study abroad are suddenly thrown up in the air. He seeks out Chu Sang Woo and is of a mind to torment him. But when the duo is forced to work together, a strange attraction starts to develop between them.
