Can you guys help me find this Omegaverse Bl manhwa
So Theres this mc that failed his entrance exam. He's at the bridge while holding his entrance paper. It flew away then the mc tried to get it but slipped. The ml caught him and found out he's an omega because of his uncontrollable pheromones. So the ml offered for them to get married because he needs to get married and theres a benifit to new weds that they would have free tuition and no entrance exam. So the mc agreed and they need like pheromone points smthin to enroll i think.
