A shade could be gorgeous, even though it is dark. This shade lives in a tree's heart. In spring, the grass came out and made friends with a tree. They became good friends. In summer, the grass became a beautiful flower and asked her tree friend about the meaning of everything around them. The tree repeatedly explained to her the conclusion: The existence itself is the most meaningful thing in this world. Then the flower accompanied the tree from the beginning of the year till she fell in winter. The flower and their friendship live in the tree's heart forever.
