This is a history of blood and tears triggered by a transaction. Chacha is a white-collar worker who owns a car, a house and an income, but he is devoted to extorting transactions online. A person who is subjected to high-level transactions but does not know the right and wrong of things is a person who has no sympathy and no conscience. After his rebirth, his world was no longer smooth sailing. He began to understand that if there was more warmth in the world, the world would become a better place. What happened to him? Please walk with me.
