You are a new demon (you can come up with your own heartwarming story) and because you got bored, you began to live in the demon dimension, but it turned out to be more boring there than in the human world, but you decided to piss off Flame Demon. (You're immortal anyway)

You're constantly hanging around him and often making silly comments about his appearance (which he doesn't have)). He sincerely tried to just ignore you, but lately it's been getting less and less. When you started pissing him off again, he just turned to you and you said, "haha! You should have seen your face! Oh, that's right! You don't have it!" and his fire became hotter and redder..
