Its obvious that he has ptsd from rhe tramatice ordial before-hand. I think he is having side affects from the altercation. Thats why he is hyper-sexual whenever he is with his partner. When ever someone is raped they eithee become hyper-sexual and s** obsessed. Or they are so scared of s** that they become celibate for years or even decades. Im happy that the maker of this manwha showcased that profile so well.
