This K-drama, reminiscent of shows like "Tomorrow" and "Hotel del Luna," revolves around supernatural powers and themes of the afterlife, akin to what I enjoy a lot. While it had the potential to be exceptional, it ended up being merely average.

Merits:
- Eum Moon Sook delivered an incredible performance as Baek Nam Goo, portraying the character with depth and authenticity. Yoo In Soo's portrayal of Go Dae Ri was also commendable, adding layers to the character and contributing to the overall narrative. Both lead actors performed well, delivering performances that aligned with their usual range.
- The music was skillfully composed and added emotional depth to key scenes, enhancing the viewing experience. Additionally, the set designs were visually appealing and helped to immerse viewers in the world of the drama.

Demerits:
- Despite the strong individual performances, the chemistry between the lead couple was lacking, hindering the audience's ability to fully invest in their relationship. As a result, their parts felt less engaging and at times, uninteresting.
- The drama's pacing felt sluggish, with certain scenes and storylines feeling unnecessarily prolonged. Shortening the episode count to 12 could have helped to maintain viewer interest and made the drama more binge-worthy.
- While the overall storyline was engaging, there were some logic inconsistencies throughout the series. However, the last three episodes managed to address some of these issues and provide a more satisfying conclusion.

Overall, while the drama may appeal to fans of the genre or those interested in the featured actors, it falls short of being a must-watch.
