Oh No! I Think I’ve Fallen for My Top-Tier Alpha Archenemy

[Two male leads + fake enemies + romantic tension + devoted to each other] Every student at Dongcheng University knows that Pei, the math department’s star, is a top-tier Alpha. Everyone assumes he’ll find an equally outstanding top-tier Omega. No one expected his boyfriend to turn out to be an unremarkable, adorable guy. Rumor has it the guy used to be Pei’s sworn enemy. Pei Yushan asks in his cool, clear voice, “They say we’re enemies. What do you think?” The supposedly unremarkable, adorable guy glares at him. “They’re blind!” Then the adorable guy throws his arms around Pei Yushan and kisses him boldly and passionately. Xu Yangkong has suffered from pheromone-blocking disorder ever since his presentation. He never imagined that the only pheromones he’d be able to tolerate in this life would belong to his sworn enemy. He resists, but when he spends time with the person who used to be his enemy, he unexpectedly discovers that his enemy isn’t a stalker, and that he... has a crush on him??
