Negishi, a high school girl who considers herself perfectly ordinary, is abruptly confessed to by a boy she has never met. Introducing himself as a long-time admirer who has finally gathered the courage to express his feelings, Hoshino asserts that everything will work out between them as long as he remains unabashedly honest with her. After rejecting Hoshino's sudden request for a date, Negishi, though bewildered yet intrigued by his candidness, agrees to walk home with him. This marks the beginning of the romantic comedy Love Roma, which chronicles the developing relationship between Hoshino, who speaks his mind with absolutely no reserve, and Negishi, who serves as the straight man to the boy's comically persistent feelings toward her.
