One day, Lin Beiyan discovered that his appearance had quietly changed, which seemed ordinary to outsiders. Then, a series of strange events happened around him... The cold and beautiful student council president turned into a cat, the sweet dance club girl shrank mysteriously, and the tsundere neighbor girl next door who had been ignoring him began to gradually become transparent. And all of this started when he opened a medical research notebook from his father. Lin Beiyan rubbed his perfect face and exclaimed: "Oh my god, I am now an expert on adolescent syndrome!?" ---- Is your youth also confused? Please be sure to open "The Story of Puberty Syndrome" so that you can prescribe the right medicine and avoid adolescent neurosis~

The earth bestows mankind with magnificent grace, and they claim to be the masters of all things. When desire, greed, hatred and killing crawl out of the wet and dark caves, the old master dies and a new king replaces them. Human beings will look forward to tomorrow and build a kingdom in deep space in the high clouds. Will that be a new era... Human beings are too forgetful. Just like in winter, they forget the heat of summer, and in summer they forget the cold of winter. --The fallen swordsman who sheathed the last ancient sword of the old era fell into the boundless darkness.
