Her Ex-Boss, His Fake Fiancé

I loved him once. I hate him now. And his fate? It’s on my ring finger. My billionaire ex-boss sabotaged the start of my company. Through a cruel twist of fate, he's now my fake fiancé. It's good for business, so I'll play...for now. There are rules, but all I seem to remember is how good it feels to be his. Should I destroy him—or surrender?
