You are mine

Being part of the student council and one of the stars among the pupils of an all boys school the pressure on Jungsu is pretty hard, especially for the upcoming exam. But somehow english just won't work out for him and when the pressure coming from his teachers gets too high he decides to cheat on the test... . But even though he gets an A- it will turn out that this decison will completely change his life. Why? Because there was a witness. And to prevent the witness to slip words to the teachers he has to obey his every wish... .
But maybe there's more to this keeping-Jungsu-as-a-slave than first meets the eye?
