Lovely K-drama and excellent, charming actors. I've watched several Chae Soo-bin dramas and I loved especially I'm Not a Robot. When it comes to Yoo Yeon-seok, I haven't had the privilege of watch him act, but certainly I will do so in the future. He does a brilliant job. Could some one pls help me to find out who's the male singer at the end of the episode 3? I tried from Spotify but I suppose it hasn't been released yet. Beautiful voice and lovely melody. K-ballads are close to my heart.
