Two male leads + dominant top + System + transmigration + cat demon + online romance
Lu Yu is a cat demon who has cultivated for a hundred years. While undergoing his tribulation to become human, he gets bound to a System and transmigrates to the modern world. Because the unreliable System bought an expired transformation potion to save money, Lu Yu's transformation fails after he takes it. Stuck in a half-human, half-demon form with cat ears, he can't complete the missions and has no choice but to pursue his target through an online relationship.
