28-year-old Sun Dapeng is addicted to gaming and used to living off his parents; even his father falling ill failed to wake him up. His parents sold the house and left, leaving only three thousand yuan to force him to face life alone. After entering the construction site, he learned a craft, but encountered an online dating scam and a wage arrears crisis. With the help of his master and fellow workers, he gradually became independent and understood responsibility and family affection. Uncle Chang's regret made him realize that cherishing cannot always wait until later. When his father fell critically ill again, Sun Dapeng stepped forward to shoulder the family, finally understanding that what his parents left behind was not indulgence, but the hope that he would grow up.
