A romance between a senior high school student and her 24-year-old math teacher. When Eva starts her senior year, caught between the drama of her ex and her best friend, she does not need for that asshole of a math teacher to add to the pile. Charles on the other hand, is just starting as a teacher at his best friend's school ( the headmaster). He has a history of always desiring the wrong people and that will once more be the case. When he meets Eva again after such a long time he can't help but bring back past histories thay he had wished to forget.
