You Tricked Me into Getting a Fake Marriage Certificate? I’ll Marry the CEO Instead. Why Are You Crying?

[Urban fantasy, no doormat protagonist, pure wish fulfillment + flash marriage + no cheating + ex's whole family regrets it + husband-chasing + love rivals] After “two years of marriage,” Gu Yuan discovers that the marriage certificate he treasured so dearly was fake. Just before graduating from college, the elegant campus beauty Lin Churan, whom he'd pursued for years, is kidnapped. Grandpa Lin publicly declares that whoever saves his granddaughter can marry her. Gu Yuan risks his life to rescue Lin Churan. Who could have known that Lin Churan's family would decide he wasn't good enough for her? They trick him with a fake marriage certificate, then deceive him into working like a horse for the Lin family. He works at the Lin Corporation by day and has to care for his sick father-in-law at night. When Gu Yuan learns the truth, he laughs in anger, turns around, and inherits a fortune worth hundreds of billions. Using his powerful connections, he throws the Lin family into chaos. But to his surprise, as he wreaks havoc, Lin Churan unexpectedly falls for him. When she sees Gu Yuan entering an arranged marriage with her lifelong nemesis, Lin Churan goes berserk. She storms into the wedding and accuses him of being a two-timing scoundrel and committing bigamy! Gu Yuan responds by throwing out the fake marriage certificate the Lin family gave him, ruining the entire family’s reputation. When Gu Yuan’s true identity as the eldest grandson of the richest man is exposed, his “former” father- and mother-in-law, his “former” brother-in-law, and his “former wife,” Lin Churan, are all stunned. Lin Churan clings to Gu Yuan's leg, crying. “Honey, I was really wrong. Forgive me. I've truly fallen in love with you. I can't live without you now.” Lin Churan's nemesis, Liu Rushuang, rises from her wheelchair and pries her fingers off one by one, smiling smugly. “Too late. He's my husband now.”
