As a good-looking Beta with a good family background, Duan Jiayan has lived a smooth sailing life for more than ten years, until he met Lu Xingci in high school. Lu Xingci’s family situation is better than his, he is taller than him and plays basketball better than him. Needless to say, his grades are a whole tier above Duan Jiayan’s. Even his friends can’t help but occasionally praise Lu Xingci. Most importantly, every girl that Duan Jiayan has set his sights on, all admitted that they have liked Lu Xingci for a few years already. Since then, Duan Jiayan has never thought well of Lu Xingci, till the day he received his new medical report. He is a late-blooming Omega, and because he became an Omega this late, it came with dire consequences. Now Alphas will feel the need to beat up other people whenever they come near Duan Jiayan. He himself is now allergic to every Alpha’s pheromone, except Lu Xingci’s.
