Takeyuki reunites with his son's ex-girlfriend, Ai, for the first time in several years. While maintaining his innocence, Takeyuki protects Ai, who has grown into an adult woman, from sexual harassment. Kenji happened to see two young men having violent and clumsy sex at his home. "I deliberately made my uncle hear a nasty voice..." Takeyuki in the past was masturbated at the mercy of a young girl. And again, he can't refuse to approach him, saying, "I wanted to meet my uncle."
