He was a Scarecrow and who cares? He was spreading his arms around the world, so lonely that he could no longer see anyone alone. When she came and found no shoulder, Scarecrow leaned his shoulder forward and said, "Here you can cry." She continued to cry from his shoulder until her life became light and she forgot her grief.
After healed her grief, Scarecrow began to see a strange, sad and purposeless scene when the world was so beautiful and colorful, so she moved on.
Scarecrow, who was previously lonely, is more lonely now, spreading his arms and crying, but He does not have a shoulder to see who can see Scarecrow's tears.
