These two stories could not be more different in plot, but are similar in the aspect of two soul mates merging into a complex dynamic. In both stories, our leads are forced to overcome the heart breaking consequences forged by their own choices, and perceptions. Neither ever truly able to let go of the other, despite how far apart life rips them. Despite knowing one has to walk away, while the other clings ardently, unwilling to accept that fate. In the end of both tales, both leads acknowledge the depth of their love, and find sanctuary in it.
Fantastic storytelling, world building, character development, action, and did such a phenomenal job of taking an already great main plot and building it into a much bigger, thoroughly organized plot arc than you ever expected.
This is the Japanese version of the K Drama, which is based off of a web novel. There is another chinese adaptation.
