A small island. There is nothing special about it except for the shining sun, clear sea and verdant forests. Subaru is an ordinary high school student who lives a peaceful life with his childhood friend Yuuhi, his English teacher Asahi, his best friend Aoba and the transfer student Minami. Everyone on the island believes their peaceful lives will last forever, until that certain day.

"A meteor will strike the earth in three months.", says a sudden announcement. There are only three months left. People panic, but they have to keep calm somehow. What will happen to them in the end?
