Very questionable family dynamics in general and the only child we see has adults be pretty snappy (if not negligent) towards him but none of it is ever the focus of a scene or plot point
There's an entire scene where the main female character gets sexually harassed at the gym. She eventually "talks back" and it's played as a "she can hold her own" moment and the harasser becomes the butt of the joke but it could still be extremely uncomfortable to some
Someone at the gym keeps being bullied by these 2 guys (1 in particular) and eventually they make it so they get him in the ring and he gets pretty severely beat up by one of them
Talks of a character "losing his eye" as he lost sight from it after a fight, more of a figure of speech. However there are a lot of cuts etc. that happen around the eyes or very near them during fights, but never the eyes directly iirc
Played as rural (and intellectual) ignorance. Absolutely no harm or malice meant by it - just thought that should be specified given the two characters' wholesome relationship (that brief exchange could still be jarring to some)
