A 13 year-old has his shirt and pants taken off and is groped by another 13 year-old in front of others at a family gathering.
Multiple children are given "re-education," which entails being made to dress in a diaper and act like a baby by an adult woman they are forced to call their mother.
A sleeping woman (a teenager, I think) is sleeping in her bed when a 13 year-old crawls in with her and puts his head in her breasts.
A woman is coerced by her employer to sleep with her employer's husband (also her employer).
Technically no? At one point, a character dresses up like a girl, and his brother falls in love with the façade. The character dressed as a girl is only doing so to further his own plans, and not out of genuine attraction. Once his brother finds out it's him he's disgusted. The brothers are not in love with each other nor do they display any romantic attraction to each other as brothers.
A woman becomes violent, using a knife to hunt a person in her home. Although she does not strike any of her family members it's clear that she would if they got in her way.
A 13 year-old (MAJOR SPOILER) stabs his mother to stop her violent rampage and then chooses to die in a fire while lying on a bed beside her (he is unsuccessful and is rescued). Before he's rescued he says that he forgives her.
A male character repeatedly dresses in women's clothes throughout the series and usually it's met with respect but in the very last episode he is laughed at. The laughter is probably meant to be because (SPOILER) a character that had had a crush on the boy disguised as a girl hadn't known until this point that the girl was a boy and also his brother. But the reason for the laughter isn't made very clear.
