He physically assaulting MC, since they were just teens until adulthood. He using any kind of method to get the MC under his control. Not just simply brotherly love. WAY BEYOND THAT. MC is his biggest weakness. In the near future MC could escape danger by playing pyschological trick to his brother. Because his brother "love" him so much, he can't see MC getting hurt. It gives him time to run and scheme something to get the main antagonist down.
So all we get to know about his brother is that he called tons of times because he's obsessive?? come on give me a bit more information, is he just obsessive about you cuz youre his brother or does he just get weird when he doesn't have control?? like give me a bit more plssssss s
