-Kim Go Eun is the female lead— and she does an amazing job in both! Her characters are dramatically different, though.
-Mystical male lead involved in some supernatural way.
-Scene where FL is "damsel in distress" and ML comes to save her. Stereotypical but still cute! (FL shows female strength in many other scenes)
-Seeing into the future / parallel universes
-amazing supporting cast
-similar aesthetic
