After I Married That Omega in My Brother's Place

[The author works hard to write, so please support the official release!] ABO story, male Alpha top and male Omega bottom Yin Yan does not top from the bottom! Song Changsi does not give birth! Yin Yan was a high-quality Alpha. In his senior year of high school, he suddenly received two pieces of terrible news. First, his biological older brother had run away from his wedding. Second, the marriage his brother had fled had landed on him. The Omega his brother had left at the altar was a domineering CEO: tall, cool and aloof, the typical rich, handsome man, and a full twelve years older than Yin Yan. A thirty-year-old Omega... Yin Yan was desperate. Was this tender young grass about to be eaten by an old bull as soon as he came of age? He was deeply opposed to the marriage and tried every way he could to cause trouble. But the Omega was perfect, equally at home hosting guests and cooking, and looked after Yin Yan with meticulous care, as if he were his own son. One day, the Omega went into heat, and Yin Yan happened to walk in on him. As a virile young man, surrounded by the scent of pheromones and gazing at the Omega's flushed cheeks and long, fair swanlike neck, Yin Yan had only one thought: charge. So he charged. Then he got charged... - Yin Hui never dreamed his younger brother would be marked by an Omega. Furious, he flew back from abroad overnight, grabbed Yin Yan, who had just finished secretly crying, and hurried straight home. The family was eating, and the Omega was there too. Without a word, Yin Hui began listing the Omega's seven deadly sins: bad temper, pettiness, scheming, a fondness for the silent treatment, and so on... The Omega listened quietly, peeling a whole plate of shrimp as he did. When Yin Hui finished, he raised his eyes to look at Yin Yan beside him. "Are you done making a fuss?" Yin Yan trembled and didn't dare answer. The Omega said, "If you're done, come eat your shrimp." Yin Yan looked at the Omega's impossibly beautiful face, then sheepishly turned to his brother. "Bro, uh, are you finished? If you are, I'll go eat the shrimp first, before they get cold." Yin Hui: "..." That very night, Yin Hui got another call from Yin Yan. "Bro, I was wrong. My butt hurts so much, waah!" Yin Hui cursed him out. "You damn well deserve it!"
