It's been a couple of years since I last have this craving-to-watch-scared-to-watch-it-end feeling (last time was with Goblin). It has a hooking feeling to it once you start episode 1.
This was beautifully made from production, cast, cinemtography, osts and whatever is in between those.
It has entered my top 5 list to binge, re-watch and recommend Kdrama's (in the romantic scifi genre).
If you have time to spare give it a go 😊
