When a Straight Man Transmigrates into a Dog-Blood ABO Novel

As a straight man, Lu Ningxing transmigrates into a melodramatic ABO novel about a beloved protagonist and three top-tier alpha love interests. Unfortunately... He becomes the protagonist's scheming, innocent-seeming younger brother. In the original story, he secretly seduces the three love interests, trying to steal them from the protagonist. To steal them, the original Lu Ningxing even secretly underwent gland surgery to hide his omega pheromones, pretending to be an alpha. He moved into the dorm with the three top-tier alpha love interests and became their roommate. System: Your mission is to seduce the three love interests by any means necessary and play the innocent-seeming schemer who tries to steal the protagonist's men. Lu Ningxing: Who's stealing men? Me? The three top-tier alphas can all tell that Lu Ningxing is a scheming, innocent-seeming alpha, and they loathe him, until The first, an arrogant and cold love interest, glares at Lu Ningxing for opening the bathroom door while he's showering. He's about to lash out when Lu Ningxing pulls out a back scrubber and asks, "Your hand's injured, so it's hard for you to scrub your back, right? Want me to help?" The second, an abstinent top student, sees that Lu Ningxing has stolen his clothes again. He's about to catch him in the act and kick him out of the dorm when Lu Ningxing pulls out a bag of laundry detergent. "Handwashing gets clothes cleaner. I washed yours too." The third, a carefree playboy, rarely comes back to the dorm. He sees Lu Ningxing skulking around his desk again and is about to go tease him. But when he gets closer, he sees Lu Ningxing putting a set of notes on his desk. "You're back. I made your class notes for the week." The three alphas gradually realize that this innocent-seeming schemer has changed. He's become... a little like a perfectly straight lotus stem. Lu Ningxing does everything he can to complete the System's mission, just so he can save enough money for gland surgery and escape this all-male dorm. The day he finally saves enough, he hears the System shout in a panic: "What did you do? Why have the three of them not only failed to fall for the protagonist and hate you, but actually fallen for you instead?" Lu Ningxing is troubled. It seems his mission has failed, but it doesn't matter. He's earned enough for gland surgery anyway. Later, Lu Ningxing realizes the failed mission is a huge problem! A really huge problem! Why do the three love interests, who were supposed to have a passionate love-hate relationship with the original protagonist, keep clinging to him? And why has his omega older brother secondary-differentiated into an alpha? Not only has he secondary-differentiated, he's also biting and marking the freshly operated gland! Reading guide: 1. The original protagonist and Lu Ningxing are not biological brothers. 2. None of the original story's three love interests ever liked the original protagonist. They only like Lu Ningxing, from beginning to end. Theme: Treat love with care
