This is a simple and perhaps clichéd story.
He said: "Qiaoqiao, you have always been a child in my heart, the child of my benefactor. Your father is the person I want to repay all my life. He has helped me for nearly ten years. In those ten years, I have never felt inferior because of poverty. I have never thought about being lazy and giving up. When I was in school, I just wanted to study. After I started business, I wanted to make a lot of money. For a poor boy with no relatives, I hope that no amount of money can get it back. The person your father cares about the most is you, You are my little sister. If you dislike me, I will try my best to make you like me. Your being hurt by love and being hospitalized showed me that you are a kind-hearted and innocent child, but at the same time, I was worried about you. At first, I only chose to take care of you to repay your family. Later, I discovered that you are so lovable and seem to be strong but need people to protect you. This is why I must be by your side."
