A fresh start turns sour after a manga editor's new boss turns out to be his ill-fated first love!
When Ritsu Onodera changes jobs, looking for a fresh start, he's not exactly thrilled when his new boss turns out to be his old flame. Ritsu's determined to leave all that in the past—but how can he when his boss is just as determined that they have a future?
Vol.5: Masamune Takano is the boss—and first love—of rookie shojo manga editor Ritsu Onodera. But Ritsu also has a fiancée, An Kohinata, whom he was betrothed to as a child. When Takano finds out about her, his relationship with Ritsu hits the rocks, but Ritsu manages to salvage the wreckage. Now Ritsu has to attend his first formal company dinner party, where he runs into An! She confesses (again), and Ritsu turns her down (again)—but this time Takano overhears An when she accuses Ritsu of stubbornly clinging to his old flame from high school, who is none other than Takano himself!
Vol.6: Masamune Takano is the boss—and first love—of rookie shojo manga editor Ritsu Onodera. One day, sick of Takafumi Yokozawa’s relentless badgering about his feelings for Takano, Ritsu snaps back that he actually hates him, not realizing Takano is nearby! In reality—and unknown to Takano—Ritsu is finally coming to terms with how he feels about his old flame. Spurred on by Ritsu’s painful words, Takano makes a clear decision regarding his relationship with Yokozawa.
 
Vol.8: Manga editor Ritsu Onodera continues toiling away for his demanding boss Masamune Takano, who happens to be his first love. The rookie editor has just finished his very first autograph session when Takano tells him he’s going to throw him a birthday party—and then promptly drags him all the way to Kyoto! Along the way, they cross paths with Arata Haitani, Takano’s old coworker who’s now the editor in chief for their rival Shonen Earth. Ritsu sees this as an opportunity to learn more about Takano’s past, but Takano demands that Ritsu steer clear of the other man!
 
Vol.10: Emerald manga editor Ritsu Onodera is still putting up with his cantankerous editor in chief—and first love!—Masamune Takano. After much objection, Ritsu’s father finally accepts his decision to break off his engagement with An. On the one hand, Ritsu’s confused about his father’s seeming indifference, while on the other, he wonders if this means he can finally determine his own future…a future with Takano, perhaps?
Vol.11: Manga editor Ritsu Onodera is still giving it his all working under his bossy editor in chief—and first love—Masamune Takano. And unfortunately, Ritsu runs—yet again—into Masamune’s nemesis Haitani, who this time asks him out! Of course, Takano is having none of it, but Haitani is quick to remind him that Ritsu isn’t his possession. Will all this pressure from his rivaling suitors finally extinguish the feelings Ritsu reluctantly carries for his old flame?
Vol.12: Manga editor Ritsu Onodera continues working under the guiding hand of his boss and first love, Masamune Takano. After the department’s fun (?) group vacation, Ritsu returns to the familiar hellscape of cycle end at Emerald. On his way to a meeting, he runs into Nao Kiyomiya, an old classmate and the only friend he had after Takano broke his heart. Will Ritsu fess up that the Masamune Saga who emotionally destroyed him in high school and the Masamune Takano he now calls his boss are one and the same?
