Sumire and Kenji are a couple who just started dating, holding hands for the first time after school. One day, Sumire visits Kenji's house to greet his father, Kensaburo. While teasing the innocent pair, Kensaburo becomes smitten with the polite and adorable Sumire. Sumire is asked by Kenji to cook for his birthday, and on that day, she makes curry. Kensaburo watches her with a lecherous gaze, mixing sleeping pills into his son's curry and aphrodisiacs into Sumire's! Pretending to be concerned about Sumire in her excited state, Kensaburo gropes her, behaving like a beast while his son sleeps soundly beside them.
