I have to live with my school bully because she is my fiancee

Fuji Hotaro was a teenager going through some bullying in school but he did not really bother himself with them much. He just let them do it since he knows that there were no ways to get out of this situation. He lives alone in his big house and would have his best find Hinami visit him. He did not live a bothersome life if he does say so himself. Then in just two days, his life takes a weird turn as he met a person he never knew and a person he knew but never expected to be in the situation as him...
