pls help me find this bl
it’s a manhwa and i only red the side stories but it’s an omega verse and the side story goes like this

there was a couple that had a forced marriage and the omega (can’t smell pheromones i think) cares for the alpha but the alpha has someone else he likes. he treated the mc like shit and told him he would mark who ever he wants. he kept getting angry at the omega and would keep blaming his pheromones and fast forward the omega was pregnant and decided to divorce him and the alpha regretted what he did so he changed his name to start a new beginning with the omega and that was how the side story ended


please help me
