Lion Ouga and horse Toshimasa are childhood friends, but after Ouga got his first heat and was caught sleeping with Toshimasa's tutor, their relationship became estranged. Now, in high school together, Toshimasa is regularly reprimanding Ouga for his immoral behavior with the herbivore students. When Ouga is forced to go to a party at Toshimasa's house, Ouga teases Toshimasa by asking, if he'll become Ouga's partner to stop his usual behavior. To his surprise, Toshimasa agrees.
