How to treat the role of fatherly love?

When I was very young, my family didn't have much money. In order to make my mother and I live a better life, my father taught himself photography. After work, he walks around taking pictures of people. I often come back late. Every day when he comes back, I will stand at the door and look around. When he came back and flew in, my father would take me home and take out my favorite chocolate from my pocket, which was absolutely extravagant for my family at that time. Although there is only one piece at a time, the feeling of being loved is very warm for me now. Later, I had a younger sister and was forced by conditions to send her to her hometown to go to school. One day, my father got up early in the morning and hurried back to his hometown without saying a word. Later, I learned that he dreamed that his sister was injured and nobody cared. My mother is not very good at cooking. When I was in the third year of high school, my father went home to make lunch for me every day. Neighbor said I don't need to look at my watch, and my father's car is more accurate than his watch. That year, he was very busy at work, and he was still preparing for the judicial examination in order to live a better life at home. I passed that year, I don't know how he did it.
