What i liked most was the male lead aka moo myong, he was not the normal obnoxious type that kdramas normally have. this drama didn't drag so many things, a problem appeared, a problem disappear immediately after a short while.. also there were no stupid cliched misunderstandings. it was straight forward However the plot wasn't as strong.and it also relied so much on eavesdropping, i bet the writers were like thank god for thin walls otherwise nothing would have moved forward in this drama. other than that this drama as amazing, the character development was amazing, they slowly changed little by little and with reason not drastically. also the romance could have been stronger, and the father son relationship could have been more emotional. i would give it a 10 but that ending was just, ah ah no..
