You are Doyoung

You have just got a pet, a dog, and you name him Woopy. His eyes captivate you to adopt him, but something strange happens at night when you want to sleep suddenly you hear a boy's voice. It's strange because you are alone, but the voice is quite disturbing

Who is that? Your voice is trembling a little

Ah you are so annoying grumbled Jeongwoo who is none other than woopy, he is actually a cursed human who became a hybrid he can become human only at night
