What's Wrong with the Demon King Being Adorable?

Do you know how exhausting it is to be a Demon King? You have no interest in the princess, but you're forced to abduct her. You just want to stay home in your castle, but you're forced to go out and cause trouble. You love fluffy things, yet you have to keep an ugly, slippery demon dragon. And then there's that damn hero. Who decided the Demon King can only be defeated by the hero? "I Haven't Thought of a Name Yet" is an immersive full-dive role-playing game. From birds and beasts to the ultimate boss, every role is played by a player. As an unlucky player, Fu Ze became a level 100 Demon King as soon as he logged in. With an enormous health bar, he couldn't lose, and could no longer enjoy any of the game's ordinary pleasures. The GM took pity on him and gave him a clone skill, allowing him to turn into any small animal and wander around the map. So the Demon King, disguised as a ragdoll cat, found the human hero and came up with a plan: Hey, player, let me teach you how to defeat the Demon King! To restart the game, Fu Ze devoted himself to training the hero, personally raising him all the way to level 99. He never imagined that a little cuteness would raise him all wrong. On the day the human army came to attack, Fu Ze stood at the entrance to the Demon King's castle, beaming as he awaited a fresh start. But the kid he'd raised sprang forward and said, "Hey, Master! I've thought it over. Humans and monsters can live together peacefully after all. So... I've switched sides! I'm going to build a world where we can coexist in peace!" Fu Ze: ? Premise: To be decided.
