Izumi and Aoi are nursery teachers at a nursery school. In fact, Izumi is a lesbian, and she fell in love at first sight with Aoi, who was hired at the same time. Today, she is going to hold a party at Izumi's house, where her husband is away on a business trip, with Rie as the director, as well as a meeting for the skit that will be shown at the nursery school's graduation ceremony. Rie, who has become disgusted with men because of her husband's DV who died 10 years ago, is also interested in Izumi and Aoi. While drinking plum wine, such three people unfolded a lewd triangle lesbian party.
