Usually, even in great series there is a bad episode or a plt twist that annoys you. Series such as was it love or familiar wife were great but this series is , for me, perfect. Great cast, plot and genuinly funny. This is THE best kdrama i have watched. It grabs you right from the beginning and never stops. Any stupid misunderstandings are resolved just as they would be in real life, not dragged out over several episodes to create false excitement. The endin was satisfactory and there were no really stupid side characters that serve no purpose.
