The prologue starts with "It was a strange dream", implying that this is just the main character dreaming, not actually happening. And it shows the female main character (in the dark) surrounded by cute cats. She's amazed by all the cats and wants to pet them. But the cats hiss as her and they want to scratch her/attack her, so she starts running towards the light, the only exit. When she reaches the light, she goes outside and sees a good-looking black haired guy (his eyes have different colors, one of his eyes is amber, the other is blue) sitting on the steps of the palace/building she just left. She thinks he looks like a cat. After that, the next scene shows a reflection of both of them, she has a normal human reflection, his reflection instead, is that of a black cat. And that's it. After that, it says "go read chapter 1!".
