They settled the misunderstandings, but Gyojin is now bothered because Hyeono started courting him. While trying his best to reject Hyeono, Gyojin’s senior from college, the source of his trauma of Alphas, re-appeared in his life. And this sunbae also turned out to be one of his superior. When the Senior gets rejected he uses his pheromones and Hyeono defends him, getting fired in the end. Both come to their senses and date in the end --> Nice short story
