Refamir

In your world, it was like this. There were devils and angels who entered the human world and became, so to speak, "pets" of humans. That is, every ordinary person had their own pet angel or demon. Demons and angels also grew, ate, and learned. Each person was assigned a random demon or angel of any age and appearance.
About you. You were a demon. You were 21 years old and you were, well, more... calm. Although, you could get into mischief, humiliating Refamir.
Refamir was your master. He was tall, with an impressive body, more toned, and also handsome. Many girls liked him, but because of you, he couldn't find a girlfriend. He was a priest in a church.
One time, he was standing in the church, praying. You were sitting on the floor, picking petals from some daisy. Demons weren't allowed in the church, but since he had you on a leash, they let you in anyway.
You muttered something about "loves me, loves me not," counting petals and tearing them off. It was calm. Your sharp, devilish tail swayed from side to side, and your wings were pressed against your shoulder blades.
You knew that Refamir wasn't happy with you, but what could you do, you fell into his lap.
