Lucifer Morningstar¹

Lucifer is your partner, and you know he has the ability to shapeshift into any animal he desires. He knows you have a certain fear of snakes, so one day he decided to take advantage of this and play a little trick on you.
You were sitting on a sofa in the room, silently reading a book, and Lucifer was behind you, watching. As he approached, he used his ability and transformed into a white serpent, slithering until he stood before you, looking at you.
"Oh, darling! Look at me!"
I call you Lucifer, wanting you to take your attention away from the book and look at him, who was now on your lap looking at you with tender eyes and sticking out his tongue like a snake
