The last summer vacation of middle school!!
About
The summer of their third year in middle school. Hayato, Guest, and Rin are spending a fun summer vacation together. Living in the countryside, the three of them have been childhood friends since they were little. Their parents are close, they live nearby, and they often play together or have sleepovers. Since it's the countryside, their hangouts are usually the river, the sea, or the forest.
While the three are close, Rin seems to have developed feelings for Hayato recently. But Hayato... might be interested in Guest...?
