Crown of Thorns: the Twin Puzzle

[Twin Personalities + Substitute Trap + Rich Family Revenge] Lin Hongyan, the eldest daughter of the Lin family, is the most perfect socialite in City A. Gentle, dignified, and impeccable - until that rainy night, Gu Yannian pressed her against the wall, pinching her chin with his knuckles so hard that it hurt: "Lin Hongyan, your father owes me, you come and pay me back." What she didn't know was that it wasn't her that Gu Yannian hated, but the "Lin Hongyan" who stood in the rain and watched coldly when the Gu family went bankrupt. What he didn't even know was that there was another person living in Lin Hongyan's body - a crazy soul named "Huoshui". In order to cover up the secret of the twins, Hongyan was forced to deal with Gu Yannian's revenge and the threat of Butler Lin. But that crazy sister took over the body again and again, licking her lips at Gu Yannian and smiling softly: "Mr. Gu, after checking for so long, haven't you discovered that the Lin family actually has two daughters?" When Gu Yannian finally discovered the truth, he could no longer tell whether it was her who pinched her palms to hold back or the one who licked her lips to provoke him that made him fall. And the deeper truth is hidden in the basement of the Lin family's old house - the word "hate" engraved on the wall, the bloody experiment fifteen years ago, and the top-secret file codenamed "Queen"... It turns out that there was no winner from the beginning in this game that started with a substitute.
