My Fair Princess: Three Lives, Three Worlds

In her first life, Xiaoyanzi was the daughter of the Heavenly Emperor and Empress, the esteemed Princess Lingxi. Betrothed to the Dragon Clan's Third Prince from childhood, she later fell in love with Moyuan, the Crown Prince of the Demon Realm.

In her second life, Xiaoyanzi and Ziwei were the emperor's daughters: one was Princess Huanzhu, the other Princess Mingzhu. But Xiaoyanzi was Qianlong's goddaughter and married Yongqi, the empress's son. After Emperor Qianlong passed away many years later, he handed the throne to Yongqi, and Xiaoyanzi became empress. Ziwei married Erkang and remained in the imperial palace.
