Transmigrated into a Book as the Female Lead's Shadow Guard

[Going VIP on the 25th! Thank you, dear readers, for your support. Three chapters will be posted that day, and there'll be an update today too.] [The main story and bonus chapters are complete. Future updates will probably just be typo fixes. If you've purchased the whole book, please leave a rating. Kisses!] Yan Shuang transmigrated into a book as a shadow guard assigned by the male lead to secretly protect the female lead. Her main job was to squat on the beams of the female lead's room every day and keep watch. This was an old-school Mary Sue novel. Every male character in the story, from a seventy-year-old man to a little boy, was attracted to the female lead. The only difference was that men who were handsome and capable enough got to appear by her side. As a professional shadow guard, Yan Shuang sometimes had to pick snow lotuses for the female lead on the Tianshan Mountains, sometimes fend off ruffians for her, and always be ready to respond whenever she was called. One day, Yan Shuang went to work as usual, dutifully crouching on the beams in the female lead's home. The female lead decided on a whim to go out for a stroll. Sure enough, trouble struck: a beggar tried to pick her purse. Just as she was struggling to pay, a top-quality male character stepped in to help. To show off, he took the female lead straight to the beggars' den. Yan Shuang saw that the little beggar was only thirteen or fourteen, painfully thin and pitiful as a monkey. The white-clad man's subordinates forced him to kowtow until his head was broken and blood poured out. Unable to bear it, Yan Shuang secretly rescued him. It was a very, very long time before she remembered that in a plotless female-lead novel like this, the only people who wouldn't be attracted to the heroine were those destined to die young as cannon fodder.
