Hitohito Tadano attends Itan Private High School as an unremarkable student in academics, athletics, and appearance, distinguished only by a white flower-shaped cowlick in his black hair. His height measures 168 cm (5'6") in his first year, increasing to 170.2 cm (5'7") by his second year. During school events, he occasionally cross-dresses as "Tadano-Kun-Chan," earning unexpected admiration from peers. In middle school, Tadano exhibited *chuunibyou* traits, styling his hair slicked-back, popping his collars, and wearing Sanskrit-printed T-shirts. He adopted the online handle "†JIN-JIN†" and believed himself exceptionally charismatic. This phase ended abruptly after classmate Kawai rejected his "LOVE" graffiti confession, dismissing him as "cringey." The humiliation led Tadano to abandon flamboyance and embrace a philosophy of extreme normalcy to avoid attention. Tadano possesses an acute ability to "read the room," interpreting subtle social cues and unspoken emotions. This skill allows him to deduce Shoko Komi's severe social anxiety on their first high school meeting. Becoming her inaugural friend, he commits to helping Komi achieve her goal of making 100 friends. He facilitates her communication by suggesting written exchanges via notebooks, later supporting her transition to verbal interactions as she gains confidence. Despite his perceptiveness, Tadano frequently overlooks romantic signals. He develops feelings for Komi early but considers himself unworthy due to his mediocrity, unaware she reciprocates. Encouraged by Rumiko Manbagi—who also harbors affection for him—Tadano confesses to Komi, initiating their relationship. Their bond fosters mutual growth: Komi becomes more assertive and expressive, while Tadano gradually abandons his self-imposed "normalcy" to pursue meaningful ambitions like teaching. Tadano resides in a small apartment with his parents and younger sister Hitomi, sharing a room with her. His mother bears the French name Jeanne Tadano, an uncommon trait in Japan. Tadano enjoys visiting historically significant old buildings and demonstrates a knack for selecting thoughtful gifts. Academically and athletically, Tadano consistently ranks average. He reluctantly serves as class representative during his first and second years due to peer pressure. Classmates initially resent his proximity to Komi, but his empathetic nature eventually earns their respect. His closest friendships include Komi, the genderfluid Najimi Osana, the intimidating yet softhearted Makoto Katai, and the observant Hiroshi Kometani.
