UPDATE after S2: This show is competing for GOAT on my list now. S2 takes on more of a single storyline, and it dials up the emotional and thriller aspects up to 11. There's one episode in particular that follows the antagonist's journey from normalcy to demonic vengefulness, which is animated in a really unique style, and with masterful and gut-wrenching storytelling. Now waiting on S3 on this main arc (gave Bridon arc a try, it's not bad but didn't keep my interest as much so it's on pause for me currently).
BTW, IMDB has the episode "Marrying by Contesting" in the wrong order as E1S12 . IIRC it should be episode 2-4 or somewhere about there.
ORIGINAL REVIEW:
This show is so well written. It sets up deep sentimental moments based on various relationships between family, friends, and lovers. If you don't cry and laugh through this series, you might not be human. The time travel compliment is definitely an interesting aspect to create the thrills and provide the story infrastructure, but the setup of emotional relationships is the series't rue strength. I never thought I'd be the type to be into sentimental dramatic scenes and payoffs, but this show has changed it for me. Would recommend to anyone.
