This TV show was refreshingly honest. The main characters are more mature and are living with real-life scars that they must accept before they can accept the other's affection. There is no chaebol drama, no formulaic unloved orphans, and no rags-to-riches background story. It's just two adults slowly, gently, funnily, stubbornly falling in love against the backdrop of their jobs and (intact!) families.
Don't get me wrong: I enjoy many of the other K-dramas, too, because I can suspend disbelief (people running into each other coincidentally in a 10 million metropolis? Rich young men feeling irresistibly attracted to poor girls rejected by their power-hungry families? One man successfully fighting off 10 hired assassins?), but for this show I didn't have to suppress my incredulity.
The sound-track was great, too. Oscar Dunbar and Rachel Yamagata are underrated singers.
