She became [Hiyori's](https://anilist.co/character/200960) stepsister after [her dad](https://anilist.co/character/260889) and [Hiyori’s mom](https://anilist.co/character/260888) remarried. She lost [her mother](https://anilist.co/character/265572) and [younger brother](https://anilist.co/character/265573) in a car accident when she was young. Koharu was born two months before Hiyori, making her the older sister (she likes to say that *a lot*). She had asthma as a child, so she couldn't go out much and was frequently hospitalized, so she spent a lot of time at home and didn't know much about playing outside.

Nervous to meet her new stepdad, Hiyori heads to the place she always feels at home—the ocean. When a curious girl named Koharu shows up, Hiyori decides to teach her how to fish, just like her father did before he died. But after Koharu reveals she’s also meeting her new family that night, the girls come to a startling realization. Their friendship is about to reach a whole new level!

When Hiyori⁠—a young girl whose deceased father taught her the joys of fishing⁠—headed out to sea for some alone time, she never thought that she would encounter another girl there.
 
After a while, this girl⁠—named Koharu⁠—and her end up fishing and cooking together, and they get to know each other a bit in the meantime. During their brief time together Koharu finds out that the reason Hiyori went out to sea that day was because she's hesitant towards meeting her new step family that same evening. But what a coincidence! Koharu is also meeting her new family tonight! "No. It can't be a coincidence..." Follow these two 'sisters' and their new life together!
