After Sam and Hoshi succeeded in making Janet and Dokyeom end up with each other, they once again went back to normal---being distant from each other, since they thought they already have no reason to talk to each other since their mission was already over. Hoshi then realized that he did not want to lose her AGAIN, and he slowly admits to himself that he actually does, like Sam. Mingyu, on the other hand, has stuck out for Sam during the days when even she would want to abandon herself. He has always been the best FRIEND Sam had always wanted. But Mingyu has always looked at Sam as more than a friend and he has always been open about his feelings but Sam always thinks it's a joke. Two friends torn up over the same girl. One girl torn up between two boys. Who will win in this epic-slash-cliché battle for Sam's heart?
