Father Tadashi always speaks up to defend his daughter-in-law every time Shiro yells, this makes the woman have feelings for her father-in-law, and the child's feelings for her father. BUT the father-in-law who is over 70 years old doesn't think so. Tadashi always thinks his son's wife likes him.

Partly Because her husband doesn't have sex often, she feels very uncomfortable every time she has a sexual attack. Partly she also wants to repay her for protecting her when her husband gets angry.
