"We promised to be together forever."
"Why?" He was always confused about her behavior, and she always did things that made him confused.
"No reason, come on!" She stretched out her little finger.

"Hang yourself with a hook, and it won't change for a hundred years!" The two little fingers were hooked together, symbolizing that their vow would never change. She was like a beautiful flower, blooming the brightest smile.
