Shuuchaku Osananajimi no Ijou Seiai: Deiai Ase Fechi wa Aijiru Susutte Ouchi Koubi de Hitotsu ni Naritai

Miu has spent her life deeply insecure about how easily she sweats, a complex that left her timid and entirely inexperienced in matters of romance. Her only source of comfort during childhood was her close friend Masazane, whom she affectionately called Chika-kun. When he asked her to become his bride one day, she gladly agreed. However, family circumstances soon forced them apart, leaving them with a single parting vow: he would return for her once they were grown. Years later, Miu is a working adult whose life suddenly falls apart when she returns home to find her house reduced to ashes. Distraught and weeping alone in a park late at night, she is approached by a familiar voice promising to take her away just as he swore he would. It is Chika-kun, finally keeping his word. Shocked but relieved, Miu moves into Masazane's home, only to discover that the devoted boy she remembers has changed drastically. He confesses an intense desire to taste her sweat, insisting she take responsibility for warping his preferences over the years. His long-suppressed childhood devotion now spills over into an overwhelming, fetish-driven obsession that refuses to be contained. Together, the highly capable younger man and the earnest woman burdened by her insecurities navigate a frustratingly sweet, intensely passionate romance under one roof, struggling to express their true feelings honestly.
