Lin Chen, a newly graduated college student, is still worried about finding a job, and his life is miserable. On this day, an uninvited guest suddenly appeared at the door of his house - Su Qing, the school beauty who was out of reach during college, actually stood in front of the door holding a pink and jade little baby, blushing and told him, "This is your daughter." Lin Chen was completely confused by the sudden appearance of his daughter and the "wife" who came to his door. Just when he was at a loss, a notification sounded in his mind. The exclusive daddy system was successfully activated. Completing the task of raising a baby would unlock generous rewards such as housing, parenting skills, and living allowances. This started Lin Chen's sweet journey of becoming a father and pursuing love.
