World's Greatest First Love manga volume 11 features story and art by Shungiku Nakamura.

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 not having any of it, but Haitani counters by reminding him that Onodera isn’t Takano’s possession. Under pressure from Haitani, and with Takano doubting Ritsu’s interest in him, will Ritsu’s true feelings for his old flame finally be extinguished?
