My Sugar Baby Turns Out to be LA's Richest Man

Isabella grew up with a father whose company paid for whatever she asked for, and she was used to money settling things. She saw Andrew once and wanted him. When she found out how poor he was, she offered to keep him, on the understanding that she was buying his affection with it. He took the arrangement, and over time it stopped being an arrangement for him. Her father's company went bankrupt without warning. The debt landed on Isabella, and Andrew stopped answering. She spent years paying it down and lived badly the whole time. She works part time in a bar now, and Andrew turns up there as the richest man in New York. She finds out she never got past the man who did her the most damage. What each of them has is the reverse of what it was when she was paying his way.
