If he hadn't kept looking for his parents, he might still be alive now. He somehow escaped the explosion that took his adoptive parents away, but he did not escape the network explosion led by his biological parents. It is different from others in breaking defense. At first, I didn't understand why he wanted his parents to buy or rent a house for him urgently and persistently. After all, I have lived in my grandparents' home for so many years, and once I find my biological parents, I will not be unable to live. However, I think it may be just a yearning for family. No matter how bad it is, parents are really responsible for him, and so is renting a house. Now I have found the answer in the suicide note, because I don't want to let go of the trafficker who sold me at the beginning, and I have already had a fight with my adoptive parents. He was sold by his biological parents, but seven or eight other children passed through the hands of this trafficker. They are likely to be trafficked. He hopes that he can help other children go home by catching traffickers. Suddenly feel very sad. He has no way out.
