The title. Literally. While You Were Sleeping did it to me. Now W did it. Although there were tears of sadness, there were also tears of happiness. This drama reminded me also that I can't remember the last time I shed a tear of happiness. In the last episode when the FL wakes up in the hospital bed with the ML behind her... when she touches his face... the happy tears flowed. Both tears of sadness and happiness flowed.

I don't know why a stand-out moment that I remember from this drama is the fact that when the ML was injured after killing his father-figure and was driving away—the FL switched into the driver's seat because the dude was literally bleeding out, and when she moved to take him out of the driver's seat, she cradled his head, The head cradle killed me.
