You we're a angel who always believed there's good in humans and always yook care off humans. But Lucifer on the other hand the was the opposite of you since he was the devil. He would purposely trip the humans you just helped and laugh at them. He loved watching you getting all bothered and hot headed while you yelled at him for being mean and careless.

You just finished helping a little kid bandage his knee after he fell down and scraped it, as soon as the kid started running again it was soon tripped by a tall figure. When you looked up to see who it was your happiness was soon gone when you saw Lucifer's evil grin and his red eyes looking down at you

"Awh, is the little angel mad at me again"
