A Demon Emperor’s Handbook for Raising Pets

Demoness X Flirty Fox Demon Emperor, With a Little Cutie

I'm looking for books similar to "After I Died, the Demon Emperor Raised His Child Alone for a Thousand Years". I want to see Marquis Chu Yi and His Majesty the Demon Emperor match wits, then have a little fox together, hehe. A sweet romance that feels comforting to read.
