The narrative commences when Shouji Fujimoto, a solitary father who yearns to become an author of children's books, interacts with Minami Takasaki, a renowned singing idol featured on the kids' educational program Oneesan to Utaou! (Let's Sing Along With Our Songstress!). As a public figure for youngsters, Minami experiences loneliness in her personal life and is strictly prohibited from romantic entanglements. Consequently, this develops into an adult love tale involving a songbird.
