love kim sohyun's dual role in this drama!! her acting saved this show along with BTOB's sungjae. when I watched this for the first time, I got angry and upset with the ending. however, after I watched this the second time, I understood where han yi an was coming from. personally among the school series, this is the best one! Nam joohyuk did a fare job of acting. oh! not forgetting, CHO SOO HYANG !! she really really really suit this role in this drama. Loving forward to kim sohyun's future upcoming works!!
