Amaetara Yurusareru tte Omotteru?

Rin works as a bank employee in Tokyo and enjoys a steady, independent life on her own. Her younger childhood friend Shoma, a popular handsome actor, constantly hangs around her apartment and clings to her like an adorable little brother. But Shoma is no longer the cute kid she remembers. Beneath his affectionate, spoiled demeanor lies the intense feelings of a man who has loved Rin for years, and he is determined to break down the boundary between them. What begins as familiar, comfortable closeness slowly turns into something far more heated as Shoma pushes past the line of childhood friends. Rin finds herself confused and flustered by the gap between the sweet younger boy she knew and the assertive man before her. This short story is a sweet yet steamy age-gap romance between a serious older woman and a devoted younger actor who refuses to be seen as just a little brother anymore.
