Being constantly bombarded with jokes from Usui Takumi saying how he will 'punish' her and her response always being how Misaki Ayuzawa would end up calling him 'an alien pervert' had become a part of their everyday life. It was simple as that. Until Misaki had discovered her grandfather's will that changed both the alien pervert's and her life. She was forced into an arranged marriage at the age of sixteen. That isn't all though. More problems arose when Usui was 'accidentally' hit by a car and woke up with a case of temporary amnesia. Would Misaki have the time to battle her schoolwork, her part time job and daily visits to the hospital where Usui is recovering from his amnesia? Or would she screw it all for the one person she loves?
