Yin Sa sometimes wonders whether his life would have been different if Yin Xiao had not returned to China. There is no Yin Xiao, no Yin family, no Su Xiu, and of course, no Yin Sa. Yin Xiao's words "I'll take care of you" back then are engraved in my bones and blood from now on, and I can never forget them again. Even if the facts change, there will always be only him by his side.
Every time Yin Xiao thinks about that year, he is always afraid. If he had not gone back that year, or if he had gone back a little later, his brother would no longer be there. He didn't even know that he had a younger brother in this world, a younger brother whom he loved to the core and loved to the core. This younger brother would become the only belief in his life.
At that time, he was 6 years old and he was 12 years old. They broke into each other's lives, and he said to him "I will take care of you." This oath blended into each other's flesh and blood and became the only one in each other's lives.
He said: You are the younger brother that I, Yin Xiao, hold in the palm of my hand all my life.
He said: You are my only brother.
