Tamahiko Shima, a self‑proclaimed pessimist, resides alone in Chiba"s mountains after a car crash left him unable to use his right hand and claimed his mother. His father and affluent kin deemed him incompetent, exiling him; he spends idle days reading and sleepless nights plagued by restless dread. Upholding the Shima family"s renowned dignity, he refuses to bring shame and accepts his new role—remain in the highlands and await death"s relief from pain.
One blustery night, Tamahiko"s insomnia breaks when a knock at the door. He discovers 14‑year‑old Yuzuki Tachibana, who declares she is destined to be his future spouse! Suddenly he recalls his father"s vow to send a bride to aid him with daily hardships.
Although she was sold as a dowry to settle her family"s debts, Yuzuki shows thoughtfulness, diligence, and devotion toward Tamahiko. Will this jaded youth embrace the gentle wind of compassion her presence offers, breaking his routine gloom?
