It's one of the best korean drama . As a foreigner, saguek dramas won't get to me . But this is filled with good talented actors who did their absolute best . Actors chemistry were the highlight . Namjihyun as always shined along with DO . She is the chemi goddess. She acts brilliantly and make us feel all the emotions of character. She plays a strong , cool,independent woman of voice . Kyungsoo acts wonderfully and his voice is so manly even a single word gives the heat. Hats off to cinematography and direction. The story is an emotional rollercoaster . Only drawback was the ending . The story was so good that all viewers wanted more so the ending felt in completed.
