Ten years ago, Xunfang harbored a secret crush on a senior one grade above her. Unfortunately, that budding romance was cut short when tragedy struck her family, forcing them apart. Ten years later, through a job recommendation from a friend, Xunfang crosses paths with that very same boy again, unexpectedly becoming his personal "nanny." As they navigate this new, chaotic dynamic, old feelings resurface, and secrets from the past begin to unravel. He tells her, "The greatest luck of my life was meeting you. If I had known our destiny began ten years ago, I would have held onto you tightly back then and never let you go. Xunfang, you are the sweet candy I have always craved."
