The story begins in the summer of a certain year
Finally one summer
The evening breeze blew across their faces. As they got to know each other, the evening breeze blew slightly and took away the youth of two boys and a girl.
During their relationship, the girl was different from before. There were many butterflies around her until she turned into a butterfly. The moment the girl disappeared, both of them returned to reality. It turned out that all this was a fantasy.
Intention: Meaning of one's own friendship
