Shōko Komi, a 15-year-old high school student, battles severe social anxiety that traps her in near-total muteness, rooted in lifelong fears of rejection and isolation. Despite widespread admiration for her elegant beauty and statuesque 168–169 cm frame, her long dark hair and porcelain features inadvertently project an unapproachable aura, masking profound vulnerability. Her silent world shifts when perceptive classmate Hitohito Tadano deciphers her struggle, pledging to help her achieve 100 friendships. Early interactions rely on notebook scribbles and paralyzing speech attempts, yet incremental breakthroughs emerge: fractured sentences during emotional peaks by year two, evolving into steadier dialogues with diminished stutters by graduation. Beneath her quiet exterior lies a paradox of acute empathy shadowed by crippling self-doubt. She internalizes blame for social missteps, oblivious to her own worth despite acts of compassion—comforting distressed infants or shielding Tadano from obsessive classmates. Romantic yearning for him simmers quietly until his confession unlocks her latent assertiveness, revealing flashes of playful flirtation. A polymath in academics and athletics, she aces exams, dominates track meets with a 6.89-second 50-meter dash, and masters cooking and cycling. Feline affinity draws her daily to a cat café, where she befriends a black cat named Chocolat. Medical records note 20/15 vision and a 48 kg athletic build. Family ties include a muted bond with her similarly reserved father, patient mentorship of her exasperating younger brother Shousuke, and buoyant encouragement from her spirited mother Shuuko. Allies like Tadano’s genderfluid childhood friend Osana Najimi and confidante Rumiko Manbagi scaffold her social growth, while navigating conflicts with obsessive admirers like Ren Yamai hones her resilience. Symbolism weaves through her narrative: cat-ear visual motifs during joy, art style fluctuations mirroring anxiety (serene detail vs. wide-eyed distress). Her name—Shōko (“glass”) Komi (“old” + “see”)—etymologically mirrors fragile perceptiveness. By graduation, tempered confidence replaces paralyzing fear, though shyness lingers. Her odyssey from silence to connection paints a delicate portrait of anxiety interwoven with incremental triumph.
