From Substitute T9 queen

For five years, Eden believed Matthew loved her. On their wedding day, she discovers the truth: she was only his girlfriend because she looks like his first love. "Married Celestine this morning. She's pregnant. You understand." Heartbroken and replaced, Eden saves a dying stranger in her ER—the notorious Rogue King. His offer? Become his contract queen for three years, and he'll make her the wealthiest woman alive. But Roland knows something Eden doesn't: she's not human, and the family who suppressed her true nature is the same one he's been hunting for twenty years.

Jane Foster's twin sister was defiled and died before her wedding. Amidst her family's crisis, Jane was called to shed her armor and marry in her sister's place, thus becoming the country's queen. The tyrant king's first love was long dead. All the concubines in the harem were merely inferior distractions. The only person he adored was the royal concubine, Lady Helena, who resembled his first love the most. Meanwhile, Jane was nothing like his first love. Everyone thought the tyrant king would get sick of her and have her dethroned sooner or later. As expected, the king and the queen were on the verge of a divorce. However, instead of the queen being on the receiving end of the divorce, it was the king. That very night, the tyrant king tugged at the hem of Jane's dress. "You can leave, but only over my dead body!" The concubines were crying their eyes out while they stopped the tyrant king and called out to Jane, "Your Majesty, please don't leave us. If you must leave, take us with you!"

My secret boyfriend, Marco Ross—the fastest rising mafia star in New York—hid a ring in our home. I thought it was for me. Instead, I received a video of him proposing to another woman—Bianco Conti —on our anniversary. The same night, masked men broke in, held me at gunpoint, and forced me to call Marco. A woman answered the call, “Marco, your little orphan is calling again.” Then Marco’s cold tone. “Don’t bother, babe, she’s just your substitute, a stray I keep around, a free woman to warm my bed.” The masked men shot me in the stomach—then fled. What Marco didn’t know? The real Conti heiress… was me. The Bianco he cherished so much… was just an imposter. I once refused to take the Conti name because of Marco, afraid it would ruin us. But if he never cared… why should I? I made one call. “Papa, I’ll come home, take over the business, and accept the marriage alliance—but Bianca has to be go.”

"You're so cheap. And you don't even have a basic sense of shame." "I am not cheap at all. You are my first man. But for her, you aren't." He cupped my neck with his hand directly and asked word by word, "What did you say?" I reached out and pinched his waist gently with my fingers, pretending to be cynical. Then I added, "And I'm clean. I don't have any other man but you. You can enjoy me as much as you want." *********************** Every woman was looking forward to marrying her beloved man. So was I. I married Patrick Cowell, the man who I had a crush on for twelve years, in the name of my sister. My sister Caroline and I were twins, but she grew up in a rich and noble family while I grew up in an orphanage. She begged me to marry Patrick as her substitute because she didn't want to marry him. I agreed sweetly. Patrick was the only heir of the richest family in this city. Handsome, rich, and powerful. However, I didn't expect that he treated me cruelly in bed as if I was his enemy. Because he knew I was not his bride? Oh no!!!

I was a street performer with no name, a ghost hired to wear a dead man’s skin. My mission was simple: Become Alexander Blackwood. Marry his icy fiancée. Sign over the forty-billion-dollar empire. In exchange, my dying sister lives. But the woman waiting at the altar isn't the socialite I was trained to seduce. She’s a wolf in silk—a twin who murdered her own sister to take her place. She doesn't want my money; she wants my soul. She knows I’m a fraud, and I know she’s a killer. In the gilded halls of the Blackwood estate, we are two monsters playing house, waiting for the first one to blink. Every night is a battlefield. Every kiss is a betrayal. She pins me to the silk sheets with the cruelty of a Queen, but when she whispers my real name in the dark, the mask slips. I was supposed to be her puppet, but I’m becoming her obsession. And as the real killers close in, I realize the only thing more dangerous than the lie we're living... is the heat of the truth. He’s a fake heir. She’s a replacement bride. In a world of silver spoons and sharpened knives, love is the deadliest sin of all.
