It is very hard for Kyou Amatsuki to justify his tedious life, but a rather persistent gal called Ai seems hellbent on not leaving him alone. And so they keep living their uneventful lives, until a sudden tragedy arrives, and a powerful realization of his own feelings makes Kyou unable to accept the tomorrow that will come. And so, he decides he will do whatever it takes to have another chance to express his feelings. He will face whatever the heavens decide to throw at him, ready to sacrifice anything to have just two minutes with her again.
