Of all the classroom projects that there were to choose from, Chanyeol,  a charismatic and outgoing guy that everyone loves, opted for the social project. He will spend a month visiting a youth center, where he is assigned to the 'patient / partner' Sung Hyeri, with which he will be forced to meet with to help her, become friends with her, and to pass the course.

At first, the idea had seemed easy until Chanyeol realized that Hyeri was not an easy person to deal with.  Strange, sly, unpredictable, unusal sense of humor and inexperience in making real friends, Hyeri accepts the challenge of confusing and driving Chanyeol crazy as if it were an experiment.

But what happens when Chanyeol realizes that Hyeri is not the crazy girl she seemed to be? When their relationship starts to be more than just school work and a crazy adventure to drive a stranger mad, and an odd friendship begins to form? When destiny takes these two characters through more embarrassing situations than they would have liked to have had?
