She once said that if there really was a Doraemon, would it be possible to go back to the past or to the future?
She once said, as long as there is an arbitrary door, I can believe that all people have never died, and all happiness has not disappeared. They will always exist in their time and space, just waiting for us to find that arbitrary door and retrieve them.
She once said, if one day I see Doraemon, I will believe it forever.
She once said, one day, I will leave.
Did I travel to an era that I never knew, or did the people around me just reappear in front of me with different identities and memories?
If time goes backwards.
When I made this wish, I wanted to go back in time and never meet him again.
But is everything really what I want?
Even if time goes back, would it really be okay?
