Rin lost her husband in a car accident. One day, when Rin was in mourning after giving up the sake he drank daily because of the sudden news of his death, his father-in-law Yoji visited Rin. Yoji, who had been extremely attached to Rin since her husband was alive, let go of all her resentment about losing her beloved son. Rin was forced to drink alcohol by Yoji. Yoji knows that when Rin drinks, he turns into a horned woman. A few minutes later, Rin, who was drunk, was with his father-in-law, whom he hated.
