What people care about from the beginning of the plot is that Pupu, Yan Liang and Zhu Chaoyang all lack fatherly love and long for fatherly love. Pupu's parents died; Yan Liang's father was arrested for fighting. When he was young, Yan Liang witnessed his father being taken away by the police, but he always maintained his father's tall image in his heart. He once thought that his father had a way to solve all the problems and even helped them raise 300,000 yuan. Although Zhu Chaoyang has a father, his father is also the father of another little girl. Outside the new family, there is not much fatherly love that can be evenly distributed to him. The only remaining fatherly love is even mixed with deception, distrust and interest exchange.

As a result, the initial series of actions of the three children revolved around fighting for the father's love. Pupu, who lost his father, suggested that "Brother Chaoyang can't be without a father like us". Pupu tricked Zhu Jingjing into "teaching" the girl on the fifth floor of the Children's Palace and told her to "stop robbing her father with Brother Chaoyang"; Zhu Chaoyang watched her sister fall from the fifth floor. She didn't save her or call the police. She is worried that her father will blame or even dislike herself when he knows. After Zhu Jingjing's death, Zhu Chaoyang still didn't wait for all his father's love, even was designed by his father and was suspected of being used, which became the turning point of his "going bad".

Father's emotional neglect and mother's emotional kidnapping are the family environment in which Zhu Chaoyang grew up. This is the reason why he is introverted and closed, but it is not the direct reason why he is "bad". Zhu Chaoyang has been living an ordinary life in such a family. When Yan Liang, the current partner, showed up at his door with Pupu, everything began to get out of control. As Zhu Chaoyang finally said, "I really regret opening the door for them." For Zhu Chaoyang, the most important thing is the valuable support environment brought by peers. In Zhiyan Chen's view, an important need of people is to be affirmed by others-my feelings are not unique to me, others have similar feelings with me, so I am normal. When one's feelings cannot resonate with others, this negative emotion will be further aggravated.
