His Darkest Obsession

One night. Two strangers. A single mistake, and her life has never been the same since.

When Siya caught her fiancée cheating on her with her step-sister, heartbroken, she runs away to Paris to clear her mind and gets drunk. That was her first mistake. Her second and more serious mistake was when she, too drunk to even form coherent sentences, had sex with some handsome stranger as a final 'fuck you' to her asshole of an ex fiancé.
She thought that it was only a one night stand, that they will just give each other a wonderful night, say goodbye and go their own ways. However, fate had other plans for her.

What she didn't know was that the man she had sex with was one of the most ruthless mafia lords in the country, and that the more time they spent away from each other after that, the more he got obsessed with her. Also, what will she do when she finds out that she is pregnant with the baby of a stranger she met on an unfortunate night?
How will they meet again?
