However, because he did not understand human nature and trusted his close relatives blindly, he was repeatedly drained and recklessly exploited by his family and relatives. In the end, his wealth was completely exhausted, he carried heavy burdens, and he met a regretful end. Experiencing Nirvana and rebirth, he returns to the very day he won the lottery. In this lifetime, he is no longer naive or innocent, and chooses to low-key guard his own opportunity, rationally planning his personal wealth and future path. Facing his family's demands and probings, he holds firm to his bottom line, stays sober and self-contained, and shakes off meaningless emotional blackmail.
