After Marrying a Cool O on a Contract, She Lost Her Memory

My aloof wife lost her memory and instantly turned into a sweet, clingy darling, but we're only married by contract!! Synopsis: Yan He hits the jackpot: she unexpectedly inherits a fortune so huge she could never spend it all in her lifetime. The sole condition is that she marry a woman she's never met. The good news: The woman is gorgeous, an aloof and sophisticated Omega, and a rising star in the business world. She's exactly Yan He's type: someone powerful, beautiful, and utterly irresistible. The bad news: She's too shrewd. Yan He doesn't like shrewd people. She feels like the woman could trick her out of her inheritance with a snap of her fingers. After they sign the marriage contract, Yan He keeps her distance, waiting for it to expire so she can divorce her wife. But instead, the first news she gets is that her wife has lost her memory in a car accident. At the hospital, Yan He sees her wife, Su Ci, again. They've only met a few times before. But Su Ci seems like a different person, affectionately calling her Hehe. Not a trace of her former coolness remains in her soft voice. Yan He is both shocked and flustered: Now that Su Ci can't remember anything, what will happen to her inheritance? After losing her memory, President Su becomes incredibly clingy. She wants hugs, constant updates on Yan He's whereabouts, and comfort when she's in heat... Not wanting to upset a patient, Yan He does her best to meet her clingy Omega's demands so Su Ci will regain her memory as soon as possible, all while desperately trying to maintain the boundaries of their contract marriage. Wait, comfort during her heat?! "Why won't you? Isn't that what a wife is supposed to do? Don't you love me anymore?" The Omega has shed all her professional polish during her heat. Her usually cool voice is now full of restraint and hurt. Yan He is trying so hard not to lose it: They're only married by contract, a contract marriage!! * In Yan He's mind, Su Ci after losing her memory is clingy and innocent, but she's still as haughty as ever deep down. No desire can overcome Su Ci's rationality, not even her heat. Until one day, Su Ci unexpectedly goes into heat. Yan He hurries home and accidentally stumbles into a hidden room: The secret compartment in the wardrobe is filled with Yan He's intimate clothing. The Omega in heat clutches them tightly, pressing them against her chest and into the bed, consumed by longing and out of control. In her panic, Yan He knocks an old diary to the floor: [She has such a beautiful smile. Her name is... Yan He? What a lovely name.] [Hehe says she wants us to be best friends. She's the only one willing to spend time with me. She's so kind. We'll be together forever, forever and ever...] [Hehe sat with someone else today. Who was that person? Why did Hehe smile at her? I want to hide Hehe away. Hehe should only smile at me...] [Hehe, where did you go? How dare you lie to me! You said you loved me and would never leave me!] [Children who lie must be punished. Cheng He, don't let me find you.] [Hehe... Hehe... Hehe...] For years, Su Ci has written her name over and over, in wild, heavy, densely packed strokes... like an Omega consumed by desire, unable to find release, obsessively calling out to the one she loves. Until one day: [I've finally found you, Hehe.] The diary ends abruptly. Yan He goes cold all over, a warning flashing through her mind: Run! But an arm wraps around her waist from behind, and the scent of hot amber breathes against the side of her neck. Su Ci strokes Yan He's cheek and studies her as an elegant vampire might admire a beautiful meal, her voice unable to hide her hurt: "Hehe, are you trying to leave me again?" * On the surface: An aloof wife loses her memory and instantly becomes a sweet, clingy darling In reality: A possessive, yandere big shot Omega acts pitiful in every way to win her wife back * Pure-hearted younger Alpha x aloof, secretly yandere older-sister Omega * No sidekicks, weak Alpha and strong Omega, neither protagonist is perfect ?? Theme: Love, the greatest redemption.
