Also to the people saying why blame the ml or ml is just a victim. He is a victim only until his sister forced him to do sex work, but to hide that fact from someone you're planning to date is where he stopped being a victim. He cant hide it from mc just becoz he dont want mc knowing his past/doesnt want to hurt yada yada, those are all excuses, everyone has the right to know what funny business their partner is upto and then its their choice whether they still want to stay. Deceiving someone can never have a happy ending.
Ml is doing this coz he probably sees it has a way to repay his sister's kindness shown in their childhood. He thinks he owes her everything thats why is willing to endure the abuse and do work that he doesn't even want to do. But he gotta understand that there are other ways to repay back, but its clear that he's been manipulated in a way where he is made to rely only on her. Hope he heals from it.
