I am still processing how the drama with such critical theme like alchemy of souls turned into a silly childish romance!! This season was pure mockery of the shadow assassin girl that we fell in love with in season 1.
It was better if naksu had died than coming back in such a miserable way. The new FL should’ve been buyeon herself not naksu with amnesia. Trying to turn her into naksu where she easily could’ve had her own identity and be a completely different character is what went wrong in this season. Two souls in one body was total nonsense.
Another big fallback is the plot, ML just let jin mu be that easily !!! Very well knowing that he used naksu as a puppet. He should’ve avenged naksu but instead his actions made no sense and had no purpose. How killing soul shifters served any purpose to him or naksu !!!
And he fell for the new FL without knowing that she was naksu, he got over her and moved on just like that. 😭 Meanwhile, yul was living in soo much pain and guilt because he couldn’t help her and do anything. Yul emerged as a true lover here. He was planning to die along with her meanwhile our ML was busy getting lovey dovey with new FL.

This season is not just average it’s bad in every way possible compared to season 1. I wish I can go back choose to not watch it and had made peace with naksu’s death in season 1.
