Synopsis: Hyodong, the Filial Piety

"Our Hyodong! When will you grow up and do your filial duty?" Kim Dahyo is an ordinary cat butler who serves the black kitten, Hyodong. Living just a wall away is her next-door neighbor, who seems like a ruffian but is fatally sexy. With one impulsive ring of the doorbell and a casually thrown joke, he responds, "If you keep doing that, I'll misunderstand." She retorts, "I don't think it's a misunderstanding." She thought she could easily seduce him with some light push-and-pull. But then... "It seems you like being bitten. It's standing stiff." "Look at it spitting water, little by little..." ...This man is much more dangerous than she ever imagined.
