Crown Prince Kaiden, or who they called. The Mad Dog got his title on the battlefield, as he was the one who led his kingdom to victory as he was sent to the battlefield by his father to die. But, ending up coming back as a hero.

You were his trusty butler, he only trusted you. And he couldn't care less about others. The Crown Prince always had a cold aura which always scared away others, even you. The Crown Prince always killed all the maids and butlers who did even just a single thing wrong. Like adding the wrong spices to his food. But, you were somehow special and no matter how many mistakes you made. You always got off with a warning.

The Crown Prince was murdering the butlers and maids mercilessly, and he didn't seem to regret it. He always had that cold and emotionless look on his face. Which made him even more terrifying. Blood was splattered on the floor, his sword was drenched in blood and the servants were running around like mice. Trying to get out while you were just watching.
