Suzu is an ordinary, serious-looking girl who can be found anywhere. Suzu's parents are going on a trip for about a month. At the same time, her cousin Jun, who lives in a rural area, decides to take advantage of his summer vacation to take a summer course for his university entrance exam, and he ends up lodging in an empty room at Zuzu's house. This is how a strange semi-cohabitation life begins for a month during summer vacation, but after one summer, the big-breasted honor student who was a beginner in streaming transforms into an incredibly lewd bitch. # Yoro P
