However Her life was anything but happy, her fiance whom she harbored intense love for 10 years cruelly exploited her and used her as a prawn to lure a deranged murderer targeting his lover.It is a horrible thing for your loved one to betray you, especially in a tragic manner.

She finds herself reincarnated as a timid and obedient wife of a billionaire.Sophia decides she wants revenge that could ruin her fiance and lover's life.And the only way to do that was to get pregnant with her billionaire husband's child!Dexter Black was the illegitimate son of a wealthy family, their marriage was nothing but a benefit for the two families. He could choose anyone to be his bride but the moment he laid his eyes on her,he knew she was the one he wanted. Dexter knows that there is something mysterious going on around her. She got a mystifying background. But he doesn't care about who she was in the past and why they keep attacking her. All he can think of is loving her, cherishing her, locking her up so that she will never return to her past. Because he knows that he won't be able to live a moment away from her.Would their marriage be a romantic tale or utter disaster?~ Except~“Wait, let me get this straight,” she says, her voice rising.“You want me to get pregnant?”Alexander's face remains impassive. “They, yeah.”Sophia stares at him, searching for signs of a head injury or a hidden camera crew. Finding neither, she decides this must be his twisted form of play.“You're going crazy,” she announces, grabbing her things. “I'm leaving.”She's halfway to the door when his words stop her cold.“It's either you get pregnant, or they won't allow you to leave until you are,” Alexander says calmly.She pauses to process his words.

“This guy, how heavy is his taste, he’s still able to eat?” Waking up, she looked at her reflection in the mirror, explosive hair, tattoos, and a demon-like face. Look at her for more than a second and you’ll have spicy eyes (your eyes will bleed-aka she looks really ugly).

Before her rebirth, she was in love with someone else, bent on escaping, and after having relations with him, hates him deep to his bones.

After her rebirth, she looked at the beauty on the bed, seriously thinking, the one who left his shadow in the past, seemingly should be him?

In her past life, her mind was muddled. She tried to get rid of the outstandingly beautiful husband that she didn’t want, was victimized by slag men and cheap women, and her most trusted friend brainwashed her. In the end, she found people rebelling and friends deserting (isolated and alone).

In this lifetime, all of the evil people scheming and longing for her divorce should yield. Sorry but this young miss’s IQ is on the line!
