Harusame to Koi Moyou

Miu Hinata, a high school freshman, spends her busy days taking care of four younger brothers in place of her parents who are often away at work. One day, by chance, she asks her classmate, Fujita, if he would be interested in participating in the parents' relay at her brother's field day. As Miu, who has never spoken to most of the boys in her class, gets to know the mean-sounding but kind Fujita-kun, she begins to develop new feelings for him.
