Everyone's a Yandere! After My Identity Was Exposed, They Joined Forces to Hunt Me Down

I just transmigrated into the harem cultivation novel I wrote, and I'm terrified! The yandere women, demonesses, and holy maidens from the original story, who would destroy the world to win the male lead, are all watching me like hawks! As a socially anxious person, I just want to keep my head down and make it to the ending as an extra. Luckily, I awakened the golden finger 【Thousand Faces Manual】, which lets me disguise myself with an unlimited number of secret identities! For the sake of resources, I become the aloof sword immortal "Shuang" and casually save a holy maiden. She falls for me on the spot: "Compared to him, the original male lead is trash!" For the sake of a treasure, I disguise myself as the demonic young master "Ye" and play along with a demoness. She gives me her heart: "He's the only one with a true and passionate nature. I have to save him from his miserable life!" For the sake of some peace and quiet, I transform into the peerless physician "Chen" and cure a princess from the previous dynasty. She refuses to marry anyone but me: "Mr. Chen is the only person in the world who understands me!" I'm losing my mind! I just want to quietly grow stronger! Even worse, in their search for their respective "white moonlights," they start working together and turn the original plot upside down! Then one day, the holy maiden, the demoness, and the princess gather together, denounce the original male lead in public, and each confesses her love... I tremble in a corner: Help! The "Shuang," "Ye," and "Chen" they're talking about are all me! I can't keep my secret identities hidden much longer!
