Slow Loop Vol. 1

Hiyori Minagi is a first-year high school girl who enjoys fishing and uses a fly-fishing technique that she learned from her father, who became ill and passed away three years ago. One day, while fishing alone at the beach, she meets a girl named Koharu, who is excited by the unfamiliar sight of the ocean. Koharu takes an interest in Hiyori’s fishing, and the two become friends. At the end of the day, they part ways, promising to meet again. But the opportunity presents itself sooner than either had realized when they discover that they are going to be stepsisters!
