Bust to Bust

Based on the manga by Yasui Riosuke. Igawa Akira is tasked with delivering school notes to his classmate Yano Megumi, who has been absent. During the visit, he looks through her sketchbook and learns she creates yaoi manga. He observes that certain anatomical details are inaccurate, a result of her limited experience with males. In a lighthearted manner, he volunteers to provide a demonstration, which initiates a physical relationship. Complications arise with the involvement of Fukuhara Shinobu, the class president and Igawa's childhood friend, who possesses romantic feelings for him. Their teacher, Susie Fujikawa, later becomes part of the encounters as well.
