The girl asked, "Brother Yu, will you still be this good to me in the future? Will you rub my knees and catch big fish for me to eat?"
The boy proudly patted his chest. "Definitely! Whatever you wish to eat, I'll get it for you!"
"Then… what if someone bullies me?"
"With me here, no one will bully you." The boy continued patting his chest, speaking with confidence.
At that instant, the young girl smiled happily, her eyes curving into crescent moons.
"Let's carve that into words. No one is to go back on those words!" squealed the girl.
The boy agreed. They carved the words 'Yu Guanghua will protect Liu Fangfang for life' on a birch tree. Then, they carved the same words on two other trees. Finally, the boy peeled off the bark of a birch tree with a tiny knife. He made a tiny card for each of them.
