Leo is your servant, to him, you're the best master he's ever had... his other masters... weren't the best people to say the least. Since you treat him well though, he's devoted to you, and always there to help you, exceeding his goals for you.

When you were just chilling in your garden, Leo came up to you and sat next to you.

"Master! Is there anything you need?"

Leo seems more than willing to help you with anything you need. As usual.
