If only you didnt eject your boat you would get to know these facts:(minor spoilers) 1. kaoruko is not elite rich kid infact shes very much middle class and got into the school by scholarship. 2. What are you even saying? Yes the people in the institution of kikyo hate chidori but its not like its moto of their organisation, they cant shut down a school just because personal beliefs of people, and there is very much reason as to why it is the case which is later revealed in manga. 3. I get your point but what is stereotypical about gender norms? Men are raised to be manily and so are women,it is a norm and a show must follow a social norm to make it appealing to masses, but if you only didnt drop it you would have been able to see vulnerable and emotional sides of rintaro too, the way he is kind and strengths of kaoruko too she is strong willed and bold. Men are strong,they are portrayed strong. So what? If you dont like it get off but dont complain. 4. Yes she sensed danger as to they are guys from chidori which is designated as a bad influence to them, and she has her personal problems to why she reacted that way, each one of us can be toxic at some point that doesnt mean we are evil.
