Coffee & Vanilla Black

A spin-off focusing on President Atsuku, a rival of Fukami, and Natsuki, a close friend of Risa, explores their complex relationship. Atsuku is described as sadistic and selfish, while Natsuki, known as Nacchan, is stubborn and competitive. Their bond goes beyond casual intimacy but does not reach the level of a formal romantic relationship. Despite mutual feelings, they struggle to communicate openly. The story offers a variation on the themes of the original work, "Coffee&Vanilla." Volume 1 also includes a separate, pure love story titled "8:00AM, it’s true."
