In the summer vacation, he visited a deserted dam deep in the mountains, where he had a good time with his father before.

Next up: All at once 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.
