The Handsome Wolf King Is a Little Baby?

I found the Silver Wolf King badly wounded, secretly formed a contract with him, and hoped to gain the strongest battle companion around. But when the beam of light faded, the mighty wolf king who once inspired fear far and wide had become a tiny creature with soft silver fur, bewildered blue eyes, and the sweet scent of milk.

Me: ...

From then on, I was hunted by the entire beastfolk world and forced onto a nerve-racking escape while “raising a baby.” Other people send their battle pets into a fight. When I fight, I pull a soundly sleeping little wolf cub out of my arms.

Then one day, surrounded by enemies with no way out, the cub in my arms opened his icy blue eyes, shed his childish form, and became a peerlessly beautiful man who looked down upon the world. He stood in front of me to protect me. The scent of milk lingered on his fingertips, but his voice was as cold as a blade: “Who gave you the nerve to lay a hand on my person?”

Only later did I learn that the day I stumbled upon him, I hadn't formed a contract with a bodyguard, but with a king destined to conquer the world, and the one and only person to receive his tender, milk-scented affection.
