What does this mean to my brother?

First of all, my sister angered my brother just to enhance the affection between brother and sister. Because there is no smoke without fire, there is no emotional improvement without noise. Sister let brother beat him, also in order to enhance the feelings between brother and sister. Later, my brother did something wrong and was known by my sister. My sister wanted my brother to improve, so she told her parents about it. My sister thinks there is nothing wrong with her. And this time, angering my brother is not a cynical attitude. Sister is serious. I want my brother to change completely. And my sister was beaten at that time. It shouldn't be hard to find that my sister hasn't finished her defense. My sister will be beaten by her brother before she finishes her defense. She will naturally grasp her brother's hand by virtue of human psychological reflection. I naturally hurt my sister this time because of my brother's disappointing behavior towards my sister. So my sister left him alone!
