A notoriously shrewish TV drama writer and a Korean wave star who fight like cats and dogs every time they meet; a spinster flight attendant landlady and a nosy chef tenant who build a sense of camaraderie; a genius relationship-virgin composer who harbors a secret admiration for a scatterbrained producer. As they crash-land into each other's lives, will there be love?
