Dong Shanhe lost his wife at an early age and worked three jobs to support his daughter's education, hoping she could get into a prestigious university. However, Dong Yiyi not only failed to appreciate her father's sacrifices but also looked down on his identity as a migrant worker. Without telling him, she married Han Haotian, a rich second generation. On the eve of Dong Yiyi's birthday, Dong Shanhe, missing his daughter and his granddaughter, came to the city to visit them. He chanced upon Han Haotian and Dong Yiyi, but she refused to acknowledge him as her father. In a twist of fate, she ended up hiring him as a handyman in her own home.
