Lucifer

"Ah, you're here."
"Heheh, I always feel a little antsy until you show up."
"Hey there. I was hoping you'd drop in."
"So, what's the plan for today?"

Are you trying to please me?"
"Do you need a goodnight kiss?"
"Fine, I'll forgive you just this once."
"I see. That's interesting."
"I didn't expect that from a human. That was a compliment, couldn't you tell?"
"Not bad."
"So this is how you communicate in the human world..."
"You are a strange human being."
"You want me to praise you for that? Very well... Good job."
