Yuuta was 12-year-old boy, who had lost his father in the traffic accident one year ago. In the summer vacation, he visited a deserted dam deep in the mountains, where he had a good time with his father before. Suddenly a thunder storm occurred and he slipped on the ground. He lost consciousness and woke up to find a girl and an unfamiliar village. He time-traveled 30 years and reached a village, which sank at the bottom of the dam. This is Yuuta's precious memory of "another" summer vacation.

Some people revel and play in the rain; others dread it and hide at the first drop. For high school student Takao, a summer shower is a source of artistic inspiration… but when he skips school in order to sketch in a rainy garden, Takao finds an even greater muse in Yukino, an older woman who seems adrift in the world. Despite the difference in their ages and lives, they strike up a comfortable relationship that slowly evolves as they randomly meet in the same garden whenever it rains. But with the rainy season coming to a close, Takao wonders if there's enough time left to put his feelings into actions and words.
