Pray in the mulberry forest and seal your love in midsummer.
The girl took the remaining warmth of her life, promised him a long life, and softly asked him to live well for her.
She was seriously ill and could not recover, and finally exchanged one life for another, leaving her eternal love in the summer of cicadas.
Yu Su kept his promise to the mulberry tree and lived alone for many years with longing and loneliness.
The seasons in the world change, but his heart will always stay in the summer with her. Finally, he goes to the appointment with himself and completes a reunion that spans the years. His love is like mulberry, and it will never end.
Concept: The mulberry tree symbolizes endless life, praying for rebirth, and corresponds to the salvation of life; a long-term agreement and a promise to live for the other party have become the shackles that trap the male protagonist throughout his life, and are also his only spiritual support in his long loneliness.
