At first glance, Yeonghan seems like an ideal boyfriend, with stellar grades and good looks, but he’s actually infamous for his awful temper. On the other hand, Yaejoon is mild-mannered and polite, and he loathes people like Yeonghan.

As the two clash and bicker, they slowly wear down each other’s walls to discover their more vulnerable sides. Will this pretend relationship eventually turn into something more genuine?
