A love story that is bound to end between Atsuko Maeda and Takahashi Minami.

With a simple reason which is Graduation.

Trying to settle things with their minds
to impossible into possible.

Flying through time to find out why?
and what happened?

but the answer will be engraved to reality years after. 

Will they find a way to contonue and trully say "for infinity and beyond"?
