The story focuses on He Ziqiu's growth trajectory. From a little boy who was abandoned by his mother and extremely insecure, under the warm acceptance of Li Haichao's family, he gradually learned to let go of the pain of the past and integrate into the new family. The story not only depicts the deep father-son relationship between him and his adoptive father Li Haichao, but also the noisy but mutually dependent childhood bond with his sister Li Jianjian and brother Ling Xiao, and also deeply explores the sensitivity and struggle deep in his heart.
As time passed, a girl named Chen Xiaocheng broke into his life. She also carries the trauma of her original family, like a little hedgehog with spikes. Similar experiences made He Ziqiu develop a strong desire to protect and resonate with her. From being cautious and testing each other at the beginning, to mutual understanding and comfort, the two finally found the missing sense of security and belonging in each other, and performed a warm and healing love story.
