Beautiful Himari Hanazawa has fallen in love with the neighbor.

Himari, who is living a happy cohabitation with thoughts of marriage, has been hurt by a bad ex-boyfriend she dated in the past. One day, unusual things began to happen, such as moving furniture in the room or running out of money. When I asked Ichiro for his opinion, he said it was just my imagination, and Himari thought it was a misunderstanding and set up a security camera as a precaution, but the room had been ransacked and a letter was written.
