The period from spring to winter is only a season for trees but a lifetime for flowers. When a lonely tree meets a newborn flower, they begin to reflect on the meaning of life. Why do we exist? Does our existence make sense? During their conversations, the flower buds, blossoms, and fades, and the tree sprouts, flourishes and sheds its leaves. They become forever warm memories in each other’s lives. In this way, the tree and the flower find their belonging and the meaning of their lives.
