Nana, who has no boyfriend, works monotonously, and finishes her twenties in a few days, learned from an in-house greeting that her best friend will leave the company, and seems to have been double betrayed. Suddenly, three bank robbers escaped into Nana's room when she returned home as usual that day. Just before I thought it was the end of my life thirty years ago, I noticed something wrong with the robbers: Takuto, Takuto's girlfriend Reira, and ex-girlfriend Aoi, who are filming their crimes with a camera while masked. If it doesn't look like a robber, what is the purpose of these three people?
