Chen Zeyun, who had called himself an A since junior high school, was unfortunately divided into an O. For the sake of his reputation with the school bully and various face issues, he resolutely became an Alpha. He takes inhibitors and blockers on time every month, and no one has discovered that he is an O so far.
Lu Chengyan was a school sweetheart who was famous for his gentleness. In fact, all the buddies who played well with him knew that he was very sultry.

From then on, the inhibitor was completely ineffective on him. In the past few times, he had been injured in fights and went to the hospital to get away. However, Lu Chengyan once went to the hospital to isolate himself during the susceptible period, and unexpectedly met Chen Zeyun in the ABO department.

"Classmate Chen, how about we make a deal. I need omega's pheromones to soothe me during my susceptible period, and you also need alpha to give you a temporary mark because of your face."
The naive Chen Zeyun agreed to this seemingly win-win deal, but...
