The Cannon-Fodder Female Lead in a Novel About a Beloved Darling [Book Transmigration]

(The blurb has been screenshotted and needs editing. Note left on 2022.12.19) Gu Yunxing transmigrated into a harem novel full of love rivals. Unfortunately, she didn't become the beloved heroine, but a cannon-fodder side character who looked a little like her. The cannon-fodder side character in this novel had a miserable fate. First, she was abducted by the first male lead, an obsessive big shot who had turned evil after failing to win the heroine's love. He forced her to be his beloved heroine's substitute and showered her with unwanted affection. Then, after finally escaping, she was rescued by the second male lead, a brilliant doctor with a deeply calculating mind. She fell into his gentle trap in the name of love, only to discover that he had been kind to her because of her rare panda blood type. In his eyes, she was nothing but a walking blood bank for the heroine. After fleeing again with a broken heart, she was found by the third male lead, an overbearing CEO, and forced into a contract marriage. She became a pawn for provoking the heroine, then was thoroughly punished by the first and second male leads, who felt sorry for the heroine. Gu Yunxing: Shivering in fear. I'm just a weak, pitiful, helpless cannon-fodder side character. Male leads, don't come near me! Go find the heroine. That's where you belong! To keep herself alive after transmigrating into the book, Gu Yunxing always stuck to one principle: cherish life and stay away from the leads. But the plot ran wild like a horse that had broken free of its reins, and all three male leads successively confessed their deep feelings for her. Gu Yunxing: ...You've all gone crazy. The three male leads were confused. Obsessive big shot: I clearly love her so much. Why does she think I see her as a substitute? Brilliant doctor: I clearly love her so much. Why does she think I'm only interested in her rare blood type? Overbearing CEO: I clearly love her so much, and proposed to her sincerely. Why does she think it's just a contract? The heroine was confused too. Wasn't she supposed to be the heroine of a harem novel full of love rivals? Weren't all three male leads supposed to revolve around her? Why had they all run off to the cannon-fodder side character? This makes no sense! Theme: Have confidence in life and refuse to accept your fate.
