The popular and mesmerising Kaede, an alpha, meets again with his old classmate Azusa, an omega who Kaede help back at the time. Azusa offers to pay back for everything and now is Kaede slave, but when Azusa goes into heat, is Kaede who is held and oblie to bite Azusa's nape.
It was kind of funny that Azusa was jealous of Hikaru after he saw the whole reaction his pheromones had on Kaede but, I mean, he has never let Kaede take him. Come on, man! If you want him to lose his mind, at least let him do you once in a while. Any way, I like it more the story of Hikaru and Ren.
