One hour before the wedding, my fiance let my best friend wear the wedding dress I designed with my own hands, smiling lightly and nonchalantly, saying it's just one size smaller and with AI face-swapping the effect is the same. Standing outside the door, I heard the whole truth—the wedding dress was intentionally made too small by him, he was certain that my parents are both dead and I am utterly dependent with no one to rely on, so I wouldn't dare make a fuss; and he also secretly stamped my private seal to give the core patent left behind by my mother to my best friend. I neither cried nor made a fuss, and only dialed another man's phone call, asking, 'I'm changing my marriage alliance partner, will you come marry me?' Retracting patents, reclaiming equipment, and playing video recordings—he thought I couldn't leave him, but little did he know that with a backhand move, I could make him lose everything.
