Can somebody tell me how his brother death happened I don't remember

think it has something to do with the other actor that took his mc's real name as his actor name? that or with the loan sharks

MC was a loan shark and he threatened a family, and the dad of that family wanted to kill someone close to MC as revenge so he tried to kill that other actor cuz they were dating at the time but then the other actor said to kill MC’s brother instead because it would hurt him more

Wait they were dating? I dont remember it at all
