Three Lives, Three Worlds, and You (GL)

Blurb 1: If my face has changed beyond recognition, if my memories are gone, among countless cycles of reincarnation, will you still recognize me? Ji Mianyue: Zhan Xue, I like you. I want to be with you forever. Zhan Xue: We bowed to Heaven and Earth by the great lake of Donghuang. Of course we'll be together forever. Luo Yue: Little fox, you're so cute. Stay by my side from now on. Bai Qian: ... Bai Qian: Wait for me to come back, and I'll marry you. Luo Yue: Okay. Ling Yue: Qianqian, you have to take responsibility for me... Bai Qian: ... Ling Yue: Qianqian, who has your heart? Bai Qian: Who else could it be but you, you bastard? Blurb 2: Three hundred years ago, a strange thing happened among the Celestial Tribe. Crown Prince Ye Hua suddenly brought a mortal back from the human realm. Before the immortals could even gossip about it, a few days later, that mortal jumped alone from the Zhuxian Platform... There were rumors that Crown Prince Ye Hua had abducted a young woman from the human realm, and when she refused to comply, she leaped from the Zhuxian Platform... Other rumors claimed that the woman was Crown Prince Ye Hua's benefactor, and that he had brought her to the Heavenly Palace to treat her illness... Perhaps the rumors became too widespread, because not long afterward, Emperor Bai Zhi and High God Zhe Yan went to the Heavenly Palace to call off the engagement. The five-hundred-century marriage pact between the Celestial Tribe and Qingqiu was finally canceled... All the immortals sighed. Crown Prince Ye Hua had always been the Heavenly Lord's pride, but who could have guessed that one rash mistake would cause such a calamity... What was even more unexpected was that after Qingqiu's Bai Qian and Crown Prince Ye Hua's engagement was canceled, they actually became good friends, leaving everyone astonished... I haven't read Three Lives, Three Worlds, The Pillow Book or the other books in the series very carefully. I've only read the novel and watched the TV drama Three Lives, Three Worlds, Ten Miles of Peach Blossoms. This story mainly follows the novel and the drama, with original elements added. No painstaking adherence to canon. Theme:
