My Nemesis Became Everyone's Favorite [Female Omega, Male Alpha]

Alpha Ruan Zhao excelled in both academics and conduct, came from a prominent family, and treated everyone with warmth and courtesy. With these three advantages, she became the perfect marriage match for countless little omegas. But everything came crashing down when the Genetic Matching Bureau sent her a report showing a 100% match. She was a 100% match with Xie Ran, an alpha and her sworn enemy. Ruan Zhao: ...? The day Xie Ran received his genetic matching report, staff from the Civil Affairs Bureau nearly dragged him off the street to register their marriage. When he stormed over to Ruan Zhao's house, he found her in her first ever heat. In front of everyone, Ruan Zhao presented as a fragile omega. The delicate Ruan Zhao pushed aside the alphas blocking her way and looked at him with teary eyes. "Have you seen my alpha?" Stunned Xie Ran: ... Before he could get a word out, the alphas in front of Ruan Zhao turned the entire place into a battlefield. They'd been enemies for years, so why had he never known that Ruan Zhao had so many admirers, even among alphas??? Content warning: The female lead changes from alpha to omega.
