father, please forgive me... Kuroki's Hearing Sound

His father-in-law Tetsuro, who lived with him, recently became sluggish and often troubled his son's wife, Tone. However, Tetsuro took it on the other hand and pretended to be wrong with his late wife, Setsuko, and attacked a chorus while taking a bath. Tetsuro, who tasted it, aimed at the time when his son was not present, licked a manko with a chord in the same way and finally invaded the lump of desire into the koto. Without telling his husband the unpleasant act with Tetsuro, he was blamed by Zurzuru and his father-in-law Chingpo.
