Reincarnated as the Heartless Empress, but I Can't Help Falling in Love

【Aloof, sharp-tongued Regent (Divine Venerable) VS innocent, quirky, heartless Empress (Demon Clan) VS devoted puppy-like sweetheart (Demon Realm’s Demon Lord) + sweet and angsty historical romance + love and hate + heroine’s growth】 Luo Shuisu, a flirtatious woman who swore she’d never marry, accidentally fell into the sea and woke up in the body of Nan Liyu, the heartless-path-practicing Empress of the Spirit Realm. Then she was told she must not fall in love, and that she would have to enter a political marriage to protect the Spirit Realm. “Your Majesty, you cultivate the heartless path!” “What?” “And today is your wedding to the Regent of the Great Jing Kingdom...” “...” After marriage, Luo Shuisu tried and failed to outwit Regent Mu Jingcheng, and gradually fell for him. Only then did she discover that he was actually a Divine Venerable from the Celestial Realm. The Demon Realm’s Demon Lord also came to follow her in the guise of an adorable puppy. Later, she learned that her journey into this body was not so simple: they had already known one another thousands of years ago... “What is true love, Divine Venerable? Do you really understand it?”
