After Divorce: Loved by the Secret Billionaire CEO

After a devastating divorce with the man she had been married to for over three years, Rachel thought her life was over. Her family disowned her, they wanted nothing to do with her anymore and she couldn't blame them. 
She had just divorced David Hart, one of the top successful bachelors in the country and heir to the Hart industries. But they would never understand that she didn't divorce him, he divorced her after she caught him cheating on her with her god-damned best friend! 
Rachel was just about to end everything by jumping off a bridge when she was saved by the most unexpected person. The boy she once bullied severally in highschool because he always wore ugly glass and was from a poor background, how come that glass make him so hot now?
Why was he helping her get revenge on ex-husband who is trying to make her life even more miserable? And most important how did he get so handsome?
What exactly does he want from her? 
... 
" No, you must want something, anything. If you can really help me get revenge on David and Lana, I can't just let you do it for free". 
Ethan went quiet for a while. 
I held my breath waiting for what his request might be.
If it was something money could buy, I'll try my best to get it for him even though I was somehow broke right now. 
"You're right I do want something". He said after thinking. 
"What?" I asked slowly. 
" Until you get your revenge on David, Lana and every other person you want, you will live here". 
What! I screamed internally. 
" Wha... What are you saying ". 
Ethan moved his face closer to mine that our nose almost touched. 
" I want you to be with me! ".
