Help pls

I'm trying to find this one manhua where it started with the girl meeting her bf in a hotel room but then they argued and the bf left and she somehow drunk/got drugged? And did boombayah with some rich man? (pls bare with me I've read this kinda plot alot so my memories just got mixed up) Then her bf came back to apologize but saw her sleeping with s1 so they broke up. Fast forward, she got pregnant and gave birth but the child is sick and need bone marrow and that's when she meet the rich men again and he can give the baby his bone marrow but she has to work for him?
