The girl who was seriously ill lay alone in the hospital bed, unwilling to be approached by anyone, until the boy's appearance seemed to be a beam of light that illuminated her whole world.
As she was discharged from the hospital, grew up, and moved, the girl only vaguely remembered having such a playmate as a child. She forgot her name and appearance. The only thing she remembered was the bottle of paper stars folded by the boy himself.
When they met again, the boy recognized the girl and said, "Hanhan, there is one missing in your star jar." He took it out of his hand and said, "Here you are, our agreement!"
Intention: The unchanging love of youth
