Returning to the countryside after a long time, Aizawa. When he goes to his family home, his childhood friend Hana, who lost her place to stay due to her parents' divorce, is living there as a lodger, and she's now using Aizawa's room. Hana, once a pure and admired figure, has transformed into a wild, impulsive girl who lives in the moment. Almost every man in the village is her fuck buddy—she's a total bitch. Aizawa just watches her from the sidelines. But on the night of the summer festival, alone together in the muggy room, unable to suppress his desires, Aizawa lunges at Hana's pussy and starts fucking her.
