Is 'The Ex-Husband' Inspired By Devil Folklore?

I've always lived in the shadow of my husband's ex because he is still in love with her. Things get to a head when he divorces me without warning not long after she comes back into his life and he gets her pregnant. Heartbroken, I decide to put myself first for once in my life, but not long after I make that decision, I find that I'm pregnant with his child as well. Five years later, our paths cross again, and this time around, the tables have turned. Not long after, secrets from five years ago begin to unravel themselves and I find out that things are not what they seemed back then after all.

She thought divorce would set her free. Instead, it led her straight into hell and the devil himself, Sebastian Sterling. He offered her salvation. What she found was sin. --- An emotional, dark romance about temptation, control, and the price of survival. -- After ending her ten-year marriage to an unfaithful husband, Rosemary Seo wants nothing more than peace. No more manipulation. No more control. Just a chance to start over with her daughter — even if it means living in a cheap motel and scraping together every cent. But when every company in town suddenly rejects her job applications, Rosie realizes she’s trapped once again — not by love, but by power. Her ex-husband’s influence stretches further than she imagined… And her only hope lies in the hands of his estranged younger brother — Sebastian Edward Sterling, a man with a reputation as dangerous as his charm. Sebastian offers her a way out. A job. A chance to rebuild. But his terms come wrapped in silk and sin — and soon, Rosie finds herself drawn into his world of temptation, control, and forbidden pleasure. “You can be my personal assistant,” he said slowly. “Take care of my daily needs.” Then his voice softened further, dangerous and intimate. “Especially in bed.” He calls it a job. She calls it a deal with the devil. Caught between survival and surrender, Rosie must decide — Will she tame the devil who wants to own her, or become his next obsession?

Heart- is the biggest traitor in our body. It makes us do the most stupid thing. And the most stupid thing I did was loving him beyond insanity. What I got in return is only disregard and betrayal.

In my past life, Killian cut off all his mistresses and spoiled me rotten, doing everything to win my hand in marriage. But the day before our wedding, I overheard him boasting to his friends. "Killian, that orphan girl you supported is still clinging to you. She's younger and prettier than your fiancée. Are you really not tempted?" Killian curled his lip in disdain, "What is she even? She isn't even fit to lick my wife's toes. Tell her to get lost." His words sent a rush of euphoria through me. He had told me himself that financing Vivienne Moore was merely a strategic move to bolster my charity foundation. At that moment, I truly believed I had found my happily ever after. But on the wedding day, the orphan girl drove her car straight into me. She sobbed and pulled out a terminal diagnosis. "Killian, I don't have much time left. I beg you. Don't abandon me, please!" I got injured in a collision and pleaded with Killian to take me to the hospital first, but he scooped her up in his arms without a second glance. "Sierra, I need to take Vivienne abroad for medical treatment. If I were her husband, it would be way easier for me to get stuff done. We have to get a divorce first. I’m sorry.” I stared at him, my eyes widening in sheer shock. He kept going, his voice stead, “I promise I'll come back and marry you in five years. Just wait for me.” Five years turned into ten, and I waited for him in vain, nothing more than a fool. It wasn't until I was on my deathbed that I received his letter, "I'm sorry, Sierra. I'll marry you in the next life." I tore the letter to shreds and died of sheer rage. Yet, when I opened my eyes again, I was back on my wedding day. I calmly gazed after Killian as they faded into the throng. Then, without hesitation, I turned around and boarded a plane to Switzerland.

She once called him her husband. Now, she calls him a devil. After catching her husband in his ex’s house one too many times, she walked away, pregnant, broken, and done. Four years later, fate laughs when she runs into him again more powerful, colder, and dangerously obsessed. He wants her back, but not for love. For revenge. For reasons buried beneath his arrogance and her silence. But as she fights the pull between hate and desire, she learns something terrifying. The devil she runs into might not be the same man she divorced. He’s darker, hungrier… and this time, he’s not letting her go.

“Just stay married to me for three years. After that, we divorce. In return, I’ll help you destroy your husband and the woman who took your child.” I agreed. Not because I was weak. But because I survived. I was once a devoted wife. Obedient. Loyal. Pregnant with a child I believed would save my marriage. Then his first love returned, and everything I trusted turned to blood and betrayal. We were rushed to the same hospital. I was bleeding. She was crying in his arms. There was only one operating room left. He chose her. He wheeled his mistress, his first love, into surgery and left me behind to miscarry alone. I lost my baby on a cold hospital bed while my husband held another woman’s hand. I divorced him. But some wounds do not heal. They sharpen. Now I have a contract marriage, a man with no love to give, and a plan written in patience and pain. I will take everything my ex-husband values, piece by piece, and make him beg for what he threw away. Forgiveness is for the dead. And I am very much alive. Watch out, husband. I will ruin you.
