Just completed this on xmas 2023, and it is better than my expectations for a romcom.
Consider this if you are looking for a drama to watch this year end - easy watch that has happy endings!

While the FL's disease/spell is far-fetched (the fantasy part), the cameos of her new identities convey meaningful messages on loving someone beyond outer appearance, dealing with unexpected happenings/ lemons in life, and embracing new identities to help others. There are heart-felt reflective moments in this romcom with a dash of fantasy.

Love the FL's performance and the exceptional friendship she have with her two buddies, and the romance of the second couple is predictably good - I kinda know and hope the second couple will get together and indeed they did.

Actually watched this drama for the ML Lee Min Ki, but was kinda disappointed. His deadpan look from Because This is My First Life (2017) seemed to have followed him in this drama. He was funny with that deadpan look in Behind Your Touch (2023), and while it was still convincing in First Life, it backfired in this drama, even though he is suffering from Prosopagnosia.
