In front of a man who wants to be a movie director, Shingo, the ghost of Mr. Kawashita, who was a senior in the college film research department who committed suicide a year ago, suddenly appears on his death anniversary. Mr. Kawashita says that he was revived because he wanted to have sex with his junior, Aoi, who had a crush on him when he was in college. In order to fulfill his desire to work with Aoi-chan, Kawashita-san and Shingo will travel back in time on that day when he was in college, which was probably the only chance for Kawashita-san to work with Aoi-chan. There was a nostalgic college Aoi-chan there. Can Mr. Kawashita redo the past and do it with Aoi-chan? It's funny, but a little sad time slip love story begins.
