This is an animated role-playing game about summer vacation in which the main character, a boy, stays in a rural town where his aunt lives for the summer vacation, where he enjoys spending his summer vacation and making friends with his sister, aunt and the children of the town.
In a town with a nostalgic atmosphere, as in one of the summer games, you can spend your summer vacation in a boyish way, swimming and fishing in the river, collecting insects and riding on the grass in the mountains, buying sweets with pocket money obtained from collecting empty bottles, playing with gum balls, gathering at a secret base and fighting bugs, and so on.
But this game is a "summer vacation secret."
There are secret events waiting for you that you can't write about in your diary.
You can pick up obscene books and videos, sneak out in the middle of the night to watch obscene shows, prank your sleeping sister and everyone else...
