Renai Kyoutei Nukegake Nashi!
恋愛協定 ～抜け駆けナシ!
Shirou, a childish student, has a crush on his teacher, Oka. His good friend Masami has always cherished him like a brother, but their mutual friend Ryuuji harbors a secret: he truly loves Masami, not Shirou. To get closer to Masami, Ryuuji pretends to also be interested in Shirou, creating a tangled web of unspoken feelings.
Masami and Ryuuji strike a gentlemen's agreement: neither of them can make a move on Shirou. However, Ryuuji has another condition—he orders Masami to take care of his sexual desires in Shirou's place. As they navigate this complicated arrangement, their true emotions and hidden agendas begin to surface, threatening their friendship and the fragile balance they have created.
