Three-year-old A Yuan was born unusually strong and with a huge appetite, yet she has always longed for a warm home. By chance, she meets Cen Shu'an, who has fallen on hard times, and decides that he is the family member she has struggled so hard to find. From then on, the unlikely pair embark on a joyful and heartwarming journey together. A Yuan's innocent kindness and optimism brighten the lives of everyone around her, while the outwardly cold but inwardly warm Cen Shu'an gradually learns to express his affection through their time together. Along the way, they make friends and help one another, building genuine family bonds through their many experiences. A Yuan finally comes to understand that a true home is not defined by blood ties, but by cherishing, accompanying, and protecting one another.
