Love in the Dark of Night

Only after Yu Huan died did she learn that she was nothing more than a vicious supporting female character, one whose sole purpose was to oppose the heroine. She was the grandson of the male supporting character's grandfather's friend. After her parents died in an accident, she was left with only her grandfather for company. The male lead's mother took pity on her for losing her parents at such a young age, brought her to live in the capital, and gave her the very best of everything. But because she had a crush on the male supporting character, she lashed out at the heroine again and again after he rejected her confession and she learned that he liked the heroine. When the apocalypse came, she even tried to shove the heroine into a horde of zombies. Her attempt failed, and she got herself killed instead. She'd been dealt a winning hand and played it terribly. After being reborn, she decided to stay away from the heroine. Everything she knew about her life later turned out to be wrong: she discovered she hadn't been reborn at all. It was all just a warning from her ancestor about the coming apocalypse. The male supporting character didn't love the heroine. He loved her. Her ancestor simply didn't want him to sweep her off her feet, so he deliberately created that dream for her. But later, she really was reborn, after being killed by the real transmigrator into the book, and came back as a pink rabbit.
