At sixteen, Shi You was diagnosed with a congenital physical defect. He had no heat cycles and couldn't sense pheromones. In other words, he was an Omega by secondary gender, but his physical traits were those of a Beta, making him a rather unusual species.
When he was eighteen, his parents dumped him at the home of a family friend, where he met Yu Qing, a guy who had no physical interest in Omegas. One day, their different lifestyles led Shi You to get into a fight with him like a cat with its fur standing on end. Halfway through, Shi You suddenly stopped choking him and asked, "Why are you wearing cologne at home on the weekend? Who are you trying to impress?"
To his surprise, Yu Qing replied, "It's not cologne. It's my pheromones."
Shi You: "...???"
"Smells good?" Yu Qing stood up, dusted off his clothes, and got ready to leave.
Still lying on his back, Shi You replied uncertainly, "It's all right. I just suddenly feel a little short of breath."
Yu Qing: "What's wrong?"
"Nothing's wrong. It's just..." Shi You tried to make sense of what was happening to his body. "It's just that when I look at you, I don't find you quite so annoying anymore."
After a few seconds of silence, Yu Qing said calmly, "My pheromones have put you into heat."
Shi You: "?"
