This spin-off chronicles the dynamic between Fukami's rival, President Akutsu, and Risa's close friend, Natsuki! It marks the start of the bond between the sadistic, selfish President Akutsu and the stubborn, competitive Nacchan, who exist in a space that is more than casual sex but less than a romantic relationship. Although they are convinced they harbor feelings for one another, they fail to express themselves honestly. Experience a slightly different bittersweet flavor from Coffee & Vanilla.
