It roughly tells the story of a boy who was a freshman in high school when he picked up a unique cherry blossom after school, so the cherry blossoms brought him to the future with another boy who was not much different in age, so he planned to help him find a way back to his own world, and finally fell in love over time.
Intention: I hope everyone can cherish everything in front of them. Once some things are lost, they will never be available again.
