Fa Solano's manga / #bullying(1)

chap 43. ouff finally, the Arch Duke came to save her just in the nick of time. and brought her to his house? mansion? estate lol I don't understand the actions of the female leads orange headed brother. he I very violent, but it's as if he doesn't understand that's a bad thing. saying at the end "as if father ever hurt you". Like...he doesn't understand pain or the fact that someone else is in pain.. I don't know. I'm very curious. was it his way of showing affection the way he was bullying her so violently. -__-
