this drama is soo goood!! i dont why its underated. the cast the graphics the supporting roles they are really good.i binged watch it in 2 days because once u start this drama u will not feel to stop it. its different from the typical cliche korean drama love story. and for those kdrama fans who gets second lead syndrome ,this series is perfect for them because the main lead and the second main lead is the same..Everyone should watch this drama
