Hyuna loves cats. Her house has two of these lovely creatures, Hoya and Moya.  One day, Hoya hurts herself. Hyuna panics and rushes her to the nearest clinic owned by a doctor named Sera. Everything will turn out fine if Hoya gets treated but the thing is… Sera doesn’t know how to treat animals. She is a doctor, not a vet. Why the hell is Moon even bringing a cat into a clinic designated for humans?
