aww

That's not how it works.... He has no education, no job experience, no family or friends, and no place of his own. His entire life has revolved around loan sharking. If he were to confront his boss, he'd risk ending up on the streets, plus he also carries the trauma of being abandoned as a newborn. Given his current condition, he definitely doesn't want to face any of that, especially not now.

But i think he has friends now. And the Ml is letting him stay at his place. He could offer to work for him.

That’s not how trauma works, he’s in sort of contractual relationship with the ml and he betrayed the other guy before and except those two there is no one. He won’t have the guts to ask for help unless it gets to him that he’s not alone and can depend on others

Hmm, good point there.

His relationship with Hajoon and Monggoo is undeniably complicated, he probably wouldn't consider relying on them fully for support as he waveringly tries to regain his footing in society, especially given the turbulent past between them and the harm he has inflicted both of them.
As for his relationship with ML, it is even more strained at the moment, especially after Jooeon told him they would sever ties once he's fully healed, so asking him for help would therefore be out of the question...
He's kinda just like a lost puppy: clinging to the only master he’s ever known, even if that said master has been nothing but abusive. Often, people with deep-seated trauma perceive enduring toxicity and pain as preferable to facing complete abandonment; which in this case leaves him trapped in the midst of the only steady but unhealthy relationship he's had for the longest— the one with his hyung.

yeah. U make a valid point.
