i find this rewatch-able value because of the amazing visual, plot, music and characters. actors were suited for the roles and performed amazingly. the visuals shook me every time, including the music. i like it because of the main characters romance between them, their will to sacrifice themselves for another. they love each other no matter what, even if their not meant to fall in love. the music is to die for !!! in my opinion, both main actors performed really well which is why they stood out. the story is kind of different from the novel, but the way they changed it is absolutely amazing. the plot is twisting. overall, its a 10/10. to me, its one of the best xianxia I've watched yet.
