Mu Yan and Mu Xu are brothers. They are 1 year apart. Their parents had a particularly fierce fight when Mu Xu was four years old and Mu Yan was three years old. It happened to be a thunderstorm, which made Mu Yan very sensitive to thunderstorms. As long as the thunder was louder, he would sleep with his brother. Later, when they entered junior high school, their relationship had already changed, but no one said it.
