Three Lives, Three Worlds, Ten Miles of Peach Blossoms Fanfiction

At first, I planned to make Siming a woman, but then I thought about it and realized that might be a little scary. The key is that Siming is such an adorable character, and I like him so much. In the end, I decided that the heroine would also be a little immortal under Donghua, and of course, the hero would be Donghua. Fengjiu and Donghua's love story really moved me. Although they didn't end up together, the ending still leaves you with a lot to ponder. Fengjiu remains a splash of color in Donghua's life, but she is no longer its most dazzling stroke. Love can burn brightly, but in the end it can't outlast the quiet flow of time. I haven't read the original novel, only watched the TV drama. So this is just an idea I had. Please don't flame me if it's not to your taste.
