"Mengmeng, stay with me and I'll treat you well."
"This old man is 68 years old. How many days does he have left? He has no children. If you can make him happy, all his savings, car, and house will be yours in the future."
Zhao Hongan patted Mengmeng's little hands, and then didn't move his hand away...
Ten years later, Mengmeng had crow's feet around her eyes: "Grandpa, didn't you have high blood pressure and heart disease ten years ago? How come you're getting more and more energetic?"
The young woman only wanted to make a short-term trade, but she ended up getting trapped.
