"Our Hyodong! When will you mature and fulfill your filial responsibilities?" Kim Dahyo is an everyday cat butler serving the black kitten, Hyodong. Residing just a wall away is her neighbor, who, despite appearing like a tough guy, possesses an alluring charm. After an impulsive press of the doorbell and a casually tossed joke, he replies, "If you keep that up, I might get the wrong idea." She responds, "I doubt it's a misunderstanding." Thinking she could effortlessly entice him with a little flirtation, she soon realizes... "It appears you enjoy being bitten. It's quite rigid." "Look at it spraying water, bit by bit..." ...This man is far more perilous than she ever anticipated.
