This is one of the best K-dramas I’ve watched in a while. While it has its flaws, the overall production was outstanding. The plot was intriguing and, for the most part, well-executed. Watching it weekly as it aired kept me thoroughly engaged, eagerly anticipating each new episode.

Pros:
Outstanding Acting:
The performances, especially from the two leads, were phenomenal. Yoo Yeon Seok delivered a masterclass in subtlety—his ability to convey deep emotions through slight facial movements and the way his voice cracked was truly remarkable. Chae Soo Bin was equally impressive, and their chemistry was absolutely perfect.

Compelling Story:
Although the script had a few issues, I loved the story. After skimming through the novel (English translation), I truly appreciated the changes the screenwriters made. I loved the drama-version of Baek Sa Eon a lot better than the novel-version. My favorite alteration was having Hong Heejoo discover earlier on that Baek Sa Eon already knew her identity as the mystery caller. This allowed for more open communication and heartwarming interactions between the couple, which I adored. The ending tied up all loose ends effectively, although it did feel slightly rushed after spending too much time on Baek Sa Eon’s disappearance.

Brilliant Storytelling:
The narrative was beautifully presented, with thoughtful parallels and shots. For example, the line “Call me when you have a corpse” was repeated three times throughout the series, each time in a different context and evoking distinct emotions from the characters. These subtle touches added depth and richness to the storytelling.

Cons: The only con I found was with inconsistencies with the script:
Aside from the usual K-drama tropes—like characters surviving falling off a cliff with no broken bones or any visible injuries or scars magically disappearing overnight—my biggest disappointment lay in the final episode. Baek Sa Eon’s six-month disappearance felt so out of character and inconsistent with the story’s progression. For someone as considerate (especially towards the FL’s feelings and well-being) and steadfast as Baek Sa Eon, it seemed implausible for him to leave the female lead in such a manner, especially over something that was not his fault and beyond his control. This was particularly jarring given how explicitly she had shared her fears of abandonment in a previous episode. While this plot point might have worked in the novel—where the two leads did not openly communicate much—it felt forced and misplaced in the drama, where their relationship was built on mutual understanding.
