How to deal with the contradiction between brother and sister?

There are a pair of very good sworn brothers and sisters. Originally, my brother was kind-hearted and my sister was innocent and lovely, and their feelings for each other were enviable. Maybe it was the bad weather, and my brother accidentally went astray. The silly sister said to her brother, "If you don't come back to the right path, we will sever the relationship between brother and sister. Since then, there has been no contact. " She wants to get her brother back in this old way. She feels that her brother still loves her, and if he follows her, he will definitely change for her. Alas, she is wrong, all wet! My brother not only refused to look back, but even agreed to break off the relationship. Oh, it's over! Later, how many times did my sister see my brother and how much she wanted to rush up. As usual, she patted him on the shoulder and called out sweetly, "Brother!" " "However, this time is different. My sister had to leave quietly, but her eyes were full of tears and her heart was full of helplessness and sadness. My sister wears a mask, a false mask, a mask of being competitive and saving face. I don't know the ending of the story, because I don't know what my brother thinks. Maybe my brother wears a mask, too! In fact, both brothers and sisters are at fault, that is, they are too proud to give in. As for me, I really hope they can be honest with each other, review each other and study the crux of the problem. Of course, children are very competitive, but brothers and sisters are not as good as friends, even if brothers say a few good words to their sisters, they will not lose face. There will inevitably be contradictions between brother and sister, but as long as they compromise with each other, work hard to get close and live in harmony, the problem will always be solved. Don't you think so?
