On the night of the reunion, a sudden heavy rain left me missing the last train and my ex-boyfriend's bad guy until the morning...

My husband is busy with work, and even on his wedding anniversary, he prioritizes work... At that moment, Nanami was informed of the alumni association. When Nanami learns that Tsukasa, her ex-boyfriend, is also present, she decides to go out of nostalgia. On the night we enjoyed the reopening, a sudden heavy rain occurred...and Tsukasa suggested, "I'll take shelter from the rain at the hotel." A depressing NTR drama in which a married woman who vowed to be pure after getting married reminds her past self as a bitch after having sex with her ex-boyfriend, and ends up having sex all night!
