Wow, she couldn't even count them all! Xie Qingxu's vision went black. From then on, her home became a battleground of jealous ex-boyfriends. Ex-boyfriend No. 1 (sarcastically): Why won't you let me in? Is someone else in there? It's fine, I can pretend I don't see them. Ex-boyfriend No. 2 (trying hard to smile): Xu Xu, you haven't used your ability in ages. Are you seeing someone new? Ex-boyfriend No. 3 (in a coy, tea-like tone): Let me stay by your side.

Upcoming novel: My Ex-Girlfriends Become Five Big Shots [One woman, multiple men; all the male leads are virgins] Qiu Zhi transmigrated into a book, becoming a wicked guide with the same name as her, a character who annoyed both the heroine and readers before repeatedly courting death in the later chapters. She would call this a catastrophic start in the history of transmigrating into a book: After being dumped when her family fell on hard times, Male Lead No. 1 made a comeback and became a domineering CEO. After being dumped because of his poor family background, Male Lead No. 2 used his brains to become a chief researcher. Male Lead No. 3, dismissed for having nothing but good looks and no brains, became the head of a certain conglomerate. Male Lead No. 4, belittled for being all brawn, earned military honors and rose to the rank of major general. Male Lead No. 5, the one she hurt most, was the empire's long-lost crown prince and was about to inherit the throne. Worst of all, she arrived in the late stages of the plot. Three days ago, she had gone all in and attacked the male lead. Now she was on her way to serve at the front lines, where she would have to work until she died, under the personal escort of Male Lead No. 4, the major general. Qiu Zhi: Talk about not leaving me any room to struggle... She had no options left, so she bowed to fate. But something was off... Why did Male Lead No. 4 ask her to become his personal guide after she'd only exchanged a couple of words with him? [Note] 1. She didn't transmigrate into someone else's body. The heroine is the original character, and everything will be explained in the book. Theme: Live together in harmony and build a harmonious society.
