Wang Xiaotang, an academic teacher at a pen-based training institution, encountered brake failure while riding his motorcycle to get off work, and crashed into a century-old sycamore tree. After waking up, she unexpectedly discovered that she had acquired the strange ability to predict sporadic fragments of the future by touching other people or objects. However, it sometimes failed to work, and the triggering method was always accompanied by embarrassing situations such as sneezing and banging her head.
From then on, her ordinary academic work and life were completely disrupted. She was forced to transform into a "sugar fairy", and in the small arena of the training institution, she hurriedly used this unreliable ability to find lost erasers for students, predict when parents would come to check, and was even pushed out to "solicit business" by the superstitious principal, causing countless ridiculous jokes and misunderstandings. In the end, Wang Xiaotang gradually learned to live with this special ability in his chaotic daily life. Not only did he find a wonderful way to turn it into a helpful tool, but he also unexpectedly gained the true meaning of friendship, love and life, and staged an urban adventure full of joy and warmth.
