If I'm not mistaken there is some stuff that get changed but not that much because I know it's adaption but for me that makes the pace at the end of that manhwa kinda too fast imo but it's also kinda bc like the mc so maybe I truly expected full exploration of his trauma at the end but it's just too flat for me, but overall that manhwa still good
The spoiler from the novel kinda crazy and I do hope this manhwa not skip so many things like "The traces of the suns" did because one thing I like when story trying to explore mc past
