Main couple: Lin Luoyu (omega) × Ji Yuan (alpha)
No one knows that the second young master of the Lin family, who appears to be a Beta, is actually an omega through and through. When someone suddenly enters his life, all his disguises are torn away in an instant, and his life takes a path completely different from the one he had imagined. He never thought that this unexpected turn would make him fall for that person. It isn't until their wedding that he finally confesses his feelings. That's when he learns that the person he loves had fallen for him when he was only ten.
Secondary couple: Lin Yu (alpha) × Gu Yan (omega)
He never imagined he would make such a serious mistake at YGQ. From then on, another person became part of his life. Only then did he realize that an otherwise dull life could be so colorful, and that the person dragged into his life because of his mistake had truly found a place in his heart. Watching him smile, Lin Yu has never regretted choosing him.
(Lin Yu and Lin Luoyu are brothers. Their alpha father and omega dad died in an accident when they were young. The omega was rescued by his own family during that accident, but they repeatedly prevented him from returning home for nine years. By the time he finally came back, the older son was already 24, and the younger son was 19.)
