And they came closer, that boy make the girl has many friends, and when they go home together, they see a sakura tree that no blooming again that season, they feels sad and now, it has already one year gone by, that cool boy say that he love the girl! And,in the moments that sakura tree bloom again.
Perhaps he will never know, but she wishes they could go back to those days, when the future seemed to be bright and there were just the two of them, and their friends, their youth, their promises.
She loves him, too.
But now, when happiness has faded and their promises have been broken, love seems just pointless.
They don't know that love is the only thing that can save them again, as it had done once.
