As an orthopedic surgeon, Wen Yan earned the right to lead operations at a remarkably young age, thanks to her sharp mind and exceptional stamina. Every day in the operating room, she swung a bone mallet with a rhythm so steady it sounded like a construction crew's chant. "Bang! Bang!" The moment she stepped out of surgery one day, her mother called with shocking news. The twin brother who was supposed to marry into the Jin family had run away before the wedding. Before disappearing, he'd left a frantic voice message. "Sis! Jin Zijin is an ice-cold demon queen! Please marry her in my place!!!" Wen Yan: "..." The Jin family were true old-money elites. Wen Yan's family had only secured the marriage through a bit of ancestral friendship. And just like that, she was "sold" into it. On their wedding night, Jin Zijin said in her usual cool, detached tone, "I'm a very traditional person. Now that we're married, everything a married couple is supposed to do... we'll do." Wen Yan nodded obediently. "O-Okay." But who was she? An orthopedic surgeon who swung hammers all day and could do fingertip push-ups wasn't about to be the one at a disadvantage. That night, the hunter became the hunted. Three days later, when the newlyweds returned to visit her parents, Wen Yan's mother took her hand with a pained expression. "Zijin's so cold and aloof. You must have had a hard time." Wen Yan stammered, "I-It's... not that bad." She remembered how Jin Zijin had melted in her arms the night before. There wasn't anything icy about her at all.
