Billionaire Dad, Don't Mess with My Mom

I must be the most miserable woman in the world!
My husband cheated on me on our wedding night! And the person he cheated on was my sister!
What's even more miserable is that I was drugged, had my virginity card taken away by a strange man, and was pregnant with the strange man's child!
Four years later, I was determined to return home for revenge!
However, when I save the billionaire from a fatal car crash, his body tells me a dangerous truth - he bears the bite marks I left on my mystery lover!
Now I'm faced with a deadly choice:
Trust the man who may share the same DNA as my children...
Or bury him before he regains his memory?
