Karen Mifune - mi suegra

My son's wife, Karen, who lives with us, angrily asked me about my son's affair. I tried to calm her down, but her anger didn't seem to go away and she started saying, "I'm going to have an affair too!" I would rather my son's wife cheat on me with another man.... The father-in-law took pity on his daughter-in-law and decided to take care of her himself!
