I'm Just a Cannon Fodder Loli, Yandere Heroine, Please Calm Down

[Single female protagonist + pure love + plot flow + variety + silly sweet loli x sickly female protagonist + not a real or fake daughter] My name is Su Xiaomian, and I traveled through time in a book about real and fake rich women, and became the cannon fodder real daughter who burped in less than ten chapters after appearing in it? So I was killed by the heroine who was a fake daughter? So, I decided to conquer the heroine and become friends with her, so that when the truth is revealed, I won't be so miserable, and I don't mind being the real daughter of a wealthy family! The most important thing is to survive! But gradually, I discovered that something was wrong with the heroine. She seemed to be a yandere and a reborn person! More importantly... The system says that I am not a real daughter, and neither is the heroine! So heroine, can't you let me go? In the dark basement. "Although you are not a real daughter, the harm you did to me in the last life was real." "So, before you double your compensation to me in this life, I will not allow anyone else to be around you. You can only look at me and like me for... A lifetime." ———— My name is Luo Yao, I am a fake daughter, I found that I was reborn after death. It seems that Su Xiaomian, the real daughter who hates selfishness, has also been reborn. But she became different from what she remembered. She can care about people, know how to say no, and is willing to drive away that annoying pair of gold-worshipping scumbags. Has she really changed? I don't seem to care. One day, that little crybaby suddenly told me that she was not a real daughter, but I actually knew it a long time ago. But that's not important, I just want to find a reason to keep her by my side and let her stay with me forever!
