Behaviour of human is mostly influenced by hormone. Men tend to do physical aggression because of their high testorone hormone. Testosterone plays major role in male aggressiveness or violence. The higher testoterone, the more aggresive they are. Level of testoterone also influence people's sensitivity, that's why most women are more sensitive and emotional than men. It needs strong will, determination, and calm mind to control behaviour influenced by hormone. I have brother, he's good and wise person but when he was angry he tended to do physical abuse, and after years he changed and admit his mistakes not to do that again. And in real life, many women who have abusive relationship still choose to stay with their partners because of certain reasons. And for someone who has stockholm syndrome like MC in this story, he choose to remember only positive traits of the ML that's why he can still fall in love with him.
*I mean, meanwhile women have higher estrogen hormone where estrogen control emotion in brain. That's why most women are more sensitive than men.
I used to think this type of stories are waaaay impossible to happen in real life until it happened to my friend he is 20 and living with 2 friends and the fuck him up and he missed work for a week and he showed up with a broken arm and wonds on his leg and other arm .. I really cant understand why someone put up to this kind of abuse especially men .. the uke should leave or kill himself better then living like this .. I hope he would not end up with any of them he need to run away from them and starts over he deserves better
