Somin is the reason I decided to finally watch this series and I enjoyed her role, which to me was that of the main/central character. I would imagine that when this series ended in 2022 that the last few scenes, especially the one where Mu Deok / Naksu is seemingly being lifted up from the depths of the lake, offered the hope of a continued role for Somin. How disappointing it must of been (and is to me now, having just finished Episode 20 a few minutes ago) to learn that Somin wasn't going to be a main character in Part 2. While Part 1 of the series was entertaining, I doubt I'll be watching Part 2.
