An amazingly well written comedy that transcends the tired time-leap trope. The combination of an unreal cast and well-written, realistic dialogue brings the characters to life, so much that you can't help but miss them by the end of the show.

The screenwriting is brilliant, the story is well paced with rising stakes, great plot twists, foreshadowing, callbacks and solid character development. The show alternates between observational and situational comedy while the underlying story has darker undertones.

The cast is absolutely awesome with a great alchemy overall. Still, Andou Sakura's performance deserves a special mention with her full-body acting style, constantly matching her posture and motion to the emotional state of her character. This alone adds to the rewatchability of the show.

The soundtrack as well as numerous references to older television drama and anime not only help ground the timeline but are sometimes part of the plot.

Overall, this show is a must-watch, easily the best drama I've seen.
