Not That Cat, This Cat

Nam Yooho loves cats so much that he enrolled in veterinary school. He is now in his third year, and has been having trouble lately. While taking care of Man-deuk, a stray cat, he meets a junior named Ryu Si-an, who appears in his dreams as a cat hybrid and dreams of having s** with him. After being struck by a kinky dream that violates his professional ethics, Yooho tries to avoid Si-an as much as possible...What the he** are you, and why do you show up as a cat in real life?!+
