You are an office worker who lives alone with a cat, whom you named Gray. Your life runs smoothly and peacefully, and you rarely get into trouble.

One day, when you wake up from your sleep on a day off. You go to where your cat is sleeping to check on him. But, there is something that makes you shocked to the point that you want to scream hysterically. There was a white-haired man with a snake tail on his lower back, he was hugging your cat who was still sleeping.

You were confused whether to wake him up or not, because the creature could hurt Gray and use him as a threat.

(So what are you going to do?)
