The 10 O'Clock Rule

For Wataru Chinen, a high school teacher with a distinct preference for cute guys, falling for his childhood friend Ryusei Yamaguchi was a complete miscalculation. Growing up, Wataru could always count on Ryusei to call every night to ensure his safety, a routine that eventually evolved into late-night pickups precisely at ten o'clock. However, the innocent boy of Wataru's youth has transformed into a capable, imposing man. When Ryusei looks at him with domineering eyes and confesses that he has always wanted to hold him, Wataru is left completely speechless. In addition to this primary romance, the volume includes several interconnected stories and doujinshi focusing on various couples. Etsu and Rio are two young students navigating the complexities of their new relationship, dealing with issues of communication, lingering insecurities regarding past partners, and the bittersweet stings of jealousy when Etsu steps into modeling. Another brief episode captures a sleepless night sparked by an irresistible invitation, while a final short piece explores why the tables turn and Etsu finds himself consumed by jealousy instead.
