Just watched episode 1 and will update when I've finished the drama.

Wanted to note that in the first episode the drama does one thing immediately better than most time travel dramas in this Melo romance genre: it creates stakes.

If the female lead (Park Minyoung) changes something about her fate then it happens to someone else. If it doesn't transfer to someone else then it will definitely happen to her. So every action is balanced.

This lends a tightness to the story I wasn't expecting.
