why be mad at Hyesung

Hyesung never hated his mother. His father is a POS. She promised him, gave him hope. She could have put the effort to talk to him going to his school or the police. He had His traumatizing life to the point that when he saw his father he fainted. If you didn't see his battle with depression then I don't think you saw the depth of the story. when it came to that rape that was Dojin. Hyesung has an identity crisis. Later Hyesung has to live with the fact that he is not mother material (broken) because of said past. Depression shows its ugly head many times throughout the story. Hyesung leaves to give Byul a better life by not being around. With the thought, he might end up being like his mother (a toy to use). Hyesung comes back tries his best. The point: A person doesn't change overnight. Hyesung is toxic to a degree and I would have liked to slap him a few times., but he got better. He came up on top and resolved his problem by sticking with the ppl that actually care for him in the present then try to cling to the past.
