Lin Ran, an online article editor, entered the updated novel she had just complained about and became the cannon fodder female supporting character Lin Qingqian. She was bound to the "dog licking system" and her task was to act as a "dog licking" in front of the male patron Gu Junlin, otherwise she would be electrocuted or killed. In order to survive, Lin Ran was forced to turn on the drama queen mode. While saying the most disgusting love words, under the guidance of the system's "BUG", he accurately took away all the opportunities that should belong to Gu Junlin.
Gu Junlin discovered that ever since this "Junior Sister Lin" appeared, his life had become strange. The opportunities he was supposed to get were always taken advantage of by her in various silly and cute ways "for your own good". He gradually began to doubt this "number one fan" and began to investigate and test her. The relationship between the two gradually heats up in the cat-and-mouse game of "she runs away, he chases".
As Lin Ran stole more and more opportunities and became stronger and stronger, the plot line of the original book completely collapsed. The real villain BOSS awakens early, and loopholes in the "rules" of the world begin to appear. A huge crisis forced these "old enemies", one in the open and the other in the dark, to the same front. In the test of life and death, Lin Ran's identity as the "book wearer" was accidentally exposed.
After their identities were exposed, the two went from being enemies who "loved and killed each other" to become true comrades-in-arms. Gu Junlin, after learning the truth that he was just a "book man", experienced tremendous pain and struggle. Finally, with the help of Lin Ran, he reinvented himself. They join forces to fight against the one who wants to swallow the whole world...
