Story :  "Kazuya... let's make a baby..." What is an omega doing at this school!?
Kazuya is a student at a prestigious high school only alphas can attend. When his new classmate Yu Misono joins his class, he finds his heart pounding and himself sweating just looking at him. Yu joins the same swim team as Kazuya. One day at practice, Kazuya goes to check on Yu who's locked himself up in the bathroom. When he enters, a sweet scent wafts out from the stall and causes Kazuya's head to spin... inside Yu had gone into heat. Kazuya's sense of reasoning goes out the window as the strong pheromones hit him... oh, how he wants to penetrate him, shove it in him, make him his, and impregnate him.
