Yuzu and Aoi work as nursery teachers. In reality, Yuzu is a lesbian and has been instantly smitten with Aoi, who was hired at the same time. Today, they are supposed to rehearse a short play for the nursery graduation ceremony, and with the principal Rie joining in, they decide to have a party at Yuzu's house since her husband is out of town on business. Rie, who has come to dislike men after her husband's domestic violence led to his death ten years ago, is also interested in Yuzu and Aoi. The three of them drink plum wine while engaging in a lewd triangular lesbian party.
