wait help… i forgot who hyunsuk is

He’s our main character’s childhood friend who is much older than him. When our main character was young, Hyunsuk took him in and had/force our male lead to be his sex toy for certain amount of time before he ditched our main character to married a woman. I think????

He's the son of MC's father's old friend/business partner. He coveted MC and after the MC's father died, his stepmom run away, left him a huge debt, he took advantage the situation, and forced/raped the 16-year-old MC, only to left him with a check of 10 million won after a month.
