I can't get this drama out of my head, I loved it so much. Plot twists keep you guessing, the acting was incredible and I adore both leads. This drama broke my heart and then glued it back together and I am so devastated that it's over. I feel so empty without it. I loved the music as well, and every episode ended in a way that made me desperate to continue. I finished this drama in three days and watched it every spare minute I had. Who cares about sleep when Derailment exists? I'm never getting over this and I wouldn't have it any other way.
