My friend's mother

When she learns about her son's bullying, her mother, Yuka, summons her bullying child, Kohei, and she sermons, but then she learns about Kohei's mother-in-law. On the other hand, Yuka apologizes for her strong scolding, saying, "If you're going to apologize, be my mother. Then I'll stop bullying." And the demands become more extreme, saying, "Let me suck on the old lady's breasts."
