Probably their past is like this.

MC dad must’ve kidnapped the ML before. That’s prolly why ML’s mouth were taped. MC accidentally saw the scene where MC dad was about to hit the ML with a bottle. That’s where MC got the scar on his neck. They became close friends and probably each other’s comforts during his abduction? And no wonder ML stepped on the photo of MC dad bedridden. Coz ML hates him. On first few chapters it’s mentioned that MC’s dad owed the brother an amount of money. So MC dad’s a $cUm? ヽ(`Д´)ノ

    My thoughts exactly!!
    I feel bad for MC, his dad is such a bad person. The old man doesn't deserve the sacrifice of his son to save him.
