He Ping and Fang Qi have been childhood sweethearts, and there was a vague love between the two. They thought they could go on forever, but they drifted apart as they grew older. He Ping has a cheerful personality and is a so-called "bad boy". He had a flamboyant personality when he was a teenager. Dropping out of school, being addicted to the Internet, and dreaming of starting a business were all his labels. However, the reality is cruel. He Ping once ran a bar, worked in real estate, his fiancée escaped from marriage, and the company was almost bankrupt. Fang Qi is a "good kid". She was admitted to a prestigious university, worked as a civil servant, and a white-collar worker. After several struggles, she finally became a lawyer. "Good boy" and "bad boy" metaphorically represent two completely different attitudes towards life. The growth process of He Ping and Fang Qi is the most typical life trajectory of the younger generation. They seek material satisfaction while also attaching importance to the enrichment of the spiritual world.
