Blossom

Once upon a time, a girl moved in a town for 3 years, just to study in a certain high school. In the garden of her house, there was a lemon tree.
The girl fell in love with a boy in her school. It was her first love. She was to shy to told him her feelings, so she just loved him in secret, and started to be friend with him. Everyday, when she was returning home, she was telling the tree how was her day, she told him about her feelings, about her growing love for the boy, and she asked him to help her, to give her the strenght to confess.
    But after 3 years, she didn't tell him her feelings. She moved to another town, and never met him again. This is what she sais to the tree, when she was about to leave:

 -" I'm sorry, I wasn't able to tell him my feelings after all. Even if you helped me so much... It's just my fault, I'm still too weak. But you know, I'm happy. I'm glad that I studied in this school, that I met him, that I met you. Talk with you everyday really helped me, without you I could not even have talked to him. So even if this may look stupid to say this to a tree...

I leave you my diary. I lost the key to open it, but I'm sure you'll find a solution. So if one day you reborn as an human, please read it and... Don't repeat my mistakes ! "

Then she burried her diary under the tree.
Her feelings reached the tree's heart, and Blossom  is born. She rememberd everything the girl told her, and writed it down in a book, that she always carry with her. She is looking for the one who will have the key to open the lock on her heart and will change her lemon blossoms in fruits.
