In "Citrus+", Yuzu Aihara, always cheerful and full of energy, and Mei Aihara, her more reserved and composed girlfriend, work to rebuild their bond after a period apart. Their friends—Harumi Taniguchi, Himeko Momokino, Nene Nomura, and others—stand by them through every challenge. Even Matsuri Mizusawa, usually their rival, now cheers for them. Mei returns after six months away, much to Yuzu’s joy. With their relationship now known, they aim to start fresh and take things step by step. Yet, obstacles remain: Mei’s duties as chairwoman of Aihara Academy and Yuzu’s plans for college. Despite these hurdles, the couple stays determined, relying on their love and support for each other to face whatever lies ahead.
