Transmigrating into the Zerg with Superpowers

Not writing this for now. I'll finish my other novel first and see if I can find the right feel. Pei Yu has enjoyed more than twenty years of smooth sailing. Then, when bad luck finally catches up with him, it hits big. He transmigrates into a novel about the insectoid race. In the novel, he's just a cannon-fodder character, while his female spouse is one of the protagonists and will later become part of the male lead's harem. After taking in his memories, Pei Yu walks out of his room and immediately sees his nominal female spouse kneeling rigidly upright. From head to toe, this is exactly his type. But Pei Yu has no intention of making a move on him. He just wants to follow the plot, then live freely. But his female spouse clings to him, eyes red as he seeks his lips. Holding him in his arms, Pei Yu thinks, Fine, I'll steal him away. It's not like I can't take on the male lead. Because of baseless rumors, Nan Si becomes a pawn in a family marriage alliance. He is about to be married off to a sickly, ugly, and violent male insect. Powerless to fight back, he chooses to submit to fate. But the male insect falls unconscious at his touch. Nan Si is pushed to the brink of despair. He thinks he'll spend the rest of his life in prison, but the male insect reaches out and pulls him to his feet. He falls into a warm embrace. One-on-one romance, mutual love, both leads are virgins, no children. Theme: Oppose unequal treatment and grow through adversity.
