Basically it's about yul asking Gyeong so to offer his ass to him if he wants beef guy to be unharmed, He was forced to strip, apologize for bad mouthing yul, And smile like how he smile when he is with beef guy during sex with yul. Yul said that Gyeon soo should never ran away again and that everytime gyeong soo sees beef guy's mark on him he should be reminded how slutty he is and there won't be second chance (second chance of him seeing beef guy and escaping yul). As for yul's plans for beef guy, I don't think he will just left the beef guy alone
Base from what I read and see not accurate but well hope it helps

Yul let his brother have his way with Gyeongsoo so he could treat him badly and Gyeongsoo would see someone that was more evil than Yul. when Yul came back his brother stopped doing it with Gyeongsoo making him believe that if he's with Yul, his brother wouldn't mess with him and that Yul would protect him. Making Gyeongsoo have feelings for Yul again.
