Hyun-jung has a boyfriend Sung-gil with a drinking problem, though he is constantly promising her that he won’t overdrink, and even writing down his promises. Their relationship is a vicious circle: Sung-gil causes a ruckus after drinking, Hyun-jung declares that she will leave him. When he sobers up, he begs her to come back to him, Hyun-jung gives him another chance, only he breaks his promise again. There is only one solution: an atomic punch from her. Atomic Punch, My Darling, a witty mixture of musical genre and fantasy, takes a humorous look at the long-lasting conflict between two lovers. (Jay Sohn)
