Li Yu is a koi spirit who has cultivated for a thousand years. Her lifelong dream is to leap through the Dragon Gate and become a dragon. But luck has never been on her side. Though she has thrown herself at it with all her might ninety-nine times, each attempt has failed at the very last moment. Just as she loses heart and believes she can never become a dragon in this life, a mysterious being calling itself the “System” suddenly appears and offers her a deal: travel to the worlds of various books and save the female leads of tragic romances, whose bodies and hearts have been abused and whose fates are cruel. As long as she completes her missions, she can accumulate merit, and once her merit is complete, she will become a dragon. Driven by her deepest desire, Li Yu accepts without hesitation and plunges into one tragic romance after another, only to have the time of her life.
Her first stop is a melodramatic CEO romance, where the original heroine is humiliated and abused by the male lead until she is exhausted in body and spirit, yet is still expected to forgive him willingly and create a so-called “happy ending.” But the one in that body now is Li Yu. She curls her lips into a sly, mischievous smile. “Come on, let's do this in reverse today and see who ends up tormenting whom!” She loves doing “good deeds without taking credit”: first, she makes the arrogant CEO suffer from foul-smelling gas and lose all face, then serves him an exclusive “poop-flavored meal,” and finally tops it off with a pair of handcuffs to send him straight to prison. After all, if you love tormenting people so much, surely you'd enjoy being tormented yourself, right?
And so Li Yu charges headlong through one tragic romance world after another, turning the original tearjerker plots upside down and having a thoroughly exhilarating time!
