Mocha Bish

Its an omegaverse where the the mc was with his ex crush but he saw his fated pair and now their together. So the mc was sad and I dont really remember much but he was in a relationship with the ml who was actually his ex crush's brother who was also fated with the same man as the brother. But the ml supressed his instincts and now hes happy with the mc. Just wanna reread it cuz its good but I can't find it

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.
