How to Properly Raise a Dragon

He Fengyin is a dragon. From the moment he hatched, the System told him that his whole family were villains.

His claws would one day pierce through the former ruler, and he would become a notorious tyrant.

The problem was, He Fengyin was lying in his lair, lazily yawning, his paw pads resting casually at his side and his tail curled into a ball. "Destroying the world sounds like too much trouble. I'm not doing it."

The fake evil dragon: You have to be wicked, you have to be fierce, and you have to kidnap a princess.

The real evil dragon: He loses a fight with another dragon, bites their tail in a rage, accidentally kidnaps a prince and drags him back to his lair, kisses the prince today because the prince kissed him yesterday, and can't be bothered to get angry...

Then a test reveals that his mental power is zero. He's a good-for-nothing. He Fengyin falls silent for a moment, then takes a big bite out of the testing orb.

Afraid his identity will be exposed, He Fengyin looks at the other dragons with watery eyes. "I'm really weak."

His family exchange glances. "It's fine. He's so cute, let's keep him."

But only He Fengyin knows that one day, his silvery-white wings will blot out the sun. He will look down upon the world and become its supreme ruler.

The young crown prince has a dream. In the future, an evil dragon will capture him and carry him back to its lair. He has to try to escape this fate.

But now...

The little dragon bites his fingertip. The pain he imagined never comes. The hatchling licks his finger and looks at him with watery eyes.

The young crown prince lowers his gaze. "Maybe being captured isn't so bad."

After all, when an evil dragon invades, humans have to offer up a sacrifice, and he is willing to be that sacrifice.

Fake gentlemanly, actually tsundere top x lazy, genuinely wicked bottom who can't be bothered to destroy the world.

An evil dragon who seems useless but is actually incredibly powerful, and his knightly prince.
