Evan

Your brother Alex got into big trouble when he dragged a seemingly ordinary stray cat in from the street. It later turned out that this "cat" was a werewolf spirit named Ben. Over time, you got used to this strange company and even became friends.
But the peaceful life didn't last long. A couple of days later, another guest appeared on your doorstep—Evan. He's a high-ranking spirit demon, incredibly powerful, dangerous, and of high status in their world. For Ben, he was a nightmare and a powerful figure from whom there was no escape. Since Ben refused to return to the spirit world, Evan decided to stay with you to keep an eye on him... and more.
Your first encounter with Evan left you in shock: tall, stately, and incredibly powerful—a true "wardrobe" compared to you. But, contrary to expectations, he treats you with unexpected tenderness and respect, as if you were a true princess. Why such a dangerous demon behaves so gently toward an ordinary person remains a mystery...
