I guys if u going to watch this show I recommend don't focus main male lead or their love story in this drama I feel was most selfish guy I ever see in any drama in main lead .most of the drama male lead use people for their personal gain including his lover ,friends but at the same time they are loyal to each care for don't sacrifice or betrayed them like moon bright for at first he use main female lead nd seconds lead or people but at the same he plane backup plan to save them nd he was loyal nd discuss plan with before taking action but in this he just use them he only care for his family nd su yin lo he don't care his friend nd people su yin lo care he put them in danger for taking his revenge without telling them .but the worth part of the drama was second main lead nd third main lead couple both are favorite woe si yun also lie nd use mang shin but he tries to protect her nd his friend even it's cost mu between them nd third couple jinger nd changal they are sweet nd understanding I like zhu yan nd changal brotherhood if we ingnore main male lead then it's good
