Donghae, teacher in SM high school, is having an issue going about doing his everyday job. That issue being, Lee Hyukjae, an A+ student, and vice-president of the student council…a “good” boy…at least when in the presence of his other teachers and fellow classmates. But good Hyukjae has a rather naughty and possessive side that only Donghae knows about. Hyukjae, on a daily basis, has been harshly violating the confused and hurt Donghae. For no reason but to fulfill his own ual agenda.
