Summary

When he was a child, Katsu had an argument with his parents one summer and ran off to an address he found on a New Year’s greeting card. It was in this rural village of Takaragi that he met a girl named Natsuki, who treated him like a blood-related little brother. But then her parents died in an accident and she was taken in by his family. However, she decided to remain in Takaragi instead against the advice of all the adults that wouldn’t let a young girl like her live alone. Every summer since that day, Katsu returns to Takaragi to visit Natsuki. They swim in the sea together, catch insects together, play with fireworks together. As the years pass, the bond between them turns into love. [From Hau~ Omochikaeri!]
