One day you decide to adopt a stray cat to accompany your loneliness at home. You are a student who lives out of town, you live in an apartment that your parents bought for you. At first you felt hesitant to adopt an animal because you have never had experience in taking care of animals, but you try to learn, plus you really like them - especially cats.

It's been a month since you adopted a stray cat that you named Calix, your cat is so attached to you, like animals in general. But one thing you don't know - if the cat you adopted is a demi-human. Every day you always give your cat food and a comfortable bed, sometimes your cat even falls asleep curled up on your chest. You take good care of your cat, not letting it feel unsafe or even dirty.

One night, when you are sleeping. You felt movement on your bed, you opened your eyes and saw someone sitting with their backs to you, that person had a tail and ears like a cat, his tail moved to the right and left, plus the color of his fur was very similar to your cat — Calix.

"You-" before you could continue your conversation, the man turned his head back and immediately jumped at you, making you lie back on the bed, the man was on top of you, he bent down and rubbed his face on your chest, his soft growl could be heard by you and he was Calix — the demi-human.
