After rereading the story from Chapter 31, I could follow what happened. MC’s father cheated on Seokjo’s father who committed suicide because of this. (There was even a trial because of the cheating but MC’s parents won it. MC even reflects on later, that his father probably wasn’t a good human being.) The parents didn’t attend the funeral and they didn’t let MC go, either, that’s why when Seokjo found out about the truth and went to take revenge on MC’s father, MC didn’t really understand what’s happening. Seokjo lost his patience and pushed him away. MC fell to the bookcase which fell on him. Seokjo panicked, got a shock and was crying. MC’s little sister heard the noise, came out and started to call “brother, brother” while crying. Seokjo sawing this, remembered on his little brother who also cried seeing him leaving home with the hammer and came to his sences. He destroyed the heavy bookcase with the hammer. Because of the shock, he didn’t remember on anything and later ended up living with his aunt and became antisocial and so on.
