Several distinct manga series share the French title Toi et Moi, each telling a different story. The search results detail three primary works.

One series, created by Nakatou Nui, is set in an all-girls high school and focuses on the relationships between four students. The narrative is split between two couples. The first pair is Seira, a loner who is cold to everyone, and Chigusa, a girl known for her parasol and frilly socks who keeps her distance from others. Isolated from their surroundings, the two become closer and begin to yearn for one another. The second pair consists of Yae, an aspiring author suffering from writers block, and Yukiyo, a girl bullied in the drama club for her looks. Together, the two best friends use their shortcomings to challenge their troubles. The story unfolds across four chapters titled Silence, Boheme, Ombrage, and Portrait, following the two couples as they befriend each other and navigate their relationships from a school picnic to rooftop conversations.

Another manga known under this French title is by author Tsukishima Haru. The story follows childhood friends Reita Kikuchi and Makoto Sakurai, who live in neighboring houses. Reita is popular with girls but also narcissistic. He announces to Makoto that he will become her boyfriend, beginning a tumultuous love story where the walls between their houses play an important role. The early chapters involve Makoto encountering a suspicious guy at a gokon (group date) from which Reita rescues her. Later chapters explore Makotos childhood and her parents divorce, which directly impacts her feelings for Reita.

A third series, titled Toi et moi, jamais, is by Mayu Sakai. It centers on Subaru, a girl entering high school after being coddled by her family her whole life, particularly by her two overprotective brothers, Tooru and Wataru. Her encounter with a classmate named Arata, who is carefree, lazy, and has a bit of a delinquent reputation, leaves her unimpressed as he is nothing like a prince charming. However, his attitude may be just a facade. The story creates a romantic triangle involving Subaru, the rebellious Arata, and the polite and wise Sakura, who has all the qualities of a prince charming. A key conflict arises from Subarus complicated relationship with her brother Wataru, who is extremely protective of her in a way that hints at deeper, potentially non-brotherly feelings. The series is completed in five volumes.
