Twenty-six-year-old programmer Lin Feng was originally a single, idle young man who was addicted to games and whose life was in a mess. His biggest goal in life was to just sit back and fish. In a sudden car accident, he lost his brother and sister-in-law overnight and was forced to become the sole guardian of his five-year-old niece Lin Yaoyao.
From changing diapers, making milk powder, to cooking and putting him to sleep, he was in a hurry and faced various situations, and was being pushed to the ground and rubbed hard by life. The stern and cold kindergarten teacher Su Wanqing exposed his embarrassment time and time again, and also secretly saw his clumsy tenderness.
The good-for-nothing uncle who once couldn't even take care of himself slowly learns to take responsibility and grow up with the little girl's unconditional trust and dependence. He went from being a "superman without power" to truly becoming someone who can protect his niece. A journey of growing up as a nanny, filled with laughter and tears, healing and warm, begins here.
