The World's Greatest First Love, Vol. 16 by Shungiku Nakamura

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?

Manga editor Ritsu Onodera believes his high school friend Nao took care of him after he collapsed due to exhaustion while working for Marukawa Publishing’s Emerald shojo magazine. But he discovers it was actually Masamune Takano, his boss—and first love!—who nursed him back to health. Ritsu decides that he’s finally going to tell Takano how he feels, but first he has to explain to Nao, who has already confessed his own love for Ritsu, that he and Nao can’t live together anymore. Will Ritsu be able to go through with it and finally confess to Takano?!
