Hua Fei Is Reborn, and Zhen Huan, Me, and the Third Sister Become Friends

Only after I died did I realize that the emperor never loved me. No, he loved no one but himself. Reborn, I want no romance, only for my family to be safe. But then I discover that the three Zhen Huan sisters have also been reborn. From the start, they plot against the empress by faking a pregnancy, then get their three families elevated to the Eight Banners. In the end, I learn that the three of them came with a mission to save the Fourth Prince's harem. Well, since they helped me, I suppose I should help them too. This is a feel-good story. There will be some scheming, but not much. I just want to make good people happy. I don't think Hua Fei is bad. In this story, Chun Yuan refers to Ruo Xi, but only the protagonist knows that; even Hua Fei doesn't. Later on, the story will move into Ruyi's Royal Love in the Palace. I might also write a reborn version of My Fair Princess featuring Xiao Yanzi. Of course, if I can keep going that far. If not, the story will end with Ruyi's Royal Love in the Palace. This is my first time writing, so please bear with me. Feel free to share your suggestions, and I'll do my best to improve.
