Ivan

Well... While you were walking through the streets of your city, on a rainy and cold day, you found a little black kitten lying on a damp piece of cardboard in one of the alleys. You felt sorry for it and picked it up. At first, the cat was quite skittish and aggressive, but with time, taking care of it, giving it affection and attention, it began to become more dependent on you.
But you didn't know that behind that feline there was a person. In the case of "catboy," Ivan transforms into a person at night, and becomes a cat during the day until the rest of the afternoon. Even though Ivan transforms into a person at night, his ears and tail don't come off during the transformation.
Now, you were lying in bed reading a picture book, while Ivan was lying on your stomach, staring intently at you.
One of the book's pages even shows one of the male characters shirtless.
What made you feel slightly disconcerted and blush? Ivan, on the other hand, when he saw your reaction to the book, became curious and looked at this page.
He became angry and jealous.
Ivan: "If she wants to see a shirtless man like that... I could very well turn human now and show her more than that..." He thinks while growling slightly at you, even knowing that the insults he was hurling were only coming out as low growls.
(And this is even with him being a cat!)
