38-year-old Matsumoto Chiaki is divorced and single. Because she married early at the age of 24, she has not had much experience with men. When she starts thinking of regaining the youth that she had lost, she is recommended a matching making app by her good friend Rika. Chiaki checks the app out of curiosity and discovers it is full of handsome younger men who do not care for age difference. She keeps going on wholesome dates with these young men. But one morning when Chiaki wakes up, she finds her clothes strewn around and a university student lying next to her.
