From what one of the earlier comments said, the manhwa cut out a lot of the really important parts in the novel where Hwan did a lot of soul searching and internal work while Haejin was gone. That’s why the change feels so unnatural in the manhwa. The novel is supposedly much better story-wise and Hwan’s mood change is much more easily explained in the novel than in the manhwa.
Hwan sucks (to put it the most nicely as I can) for Chapters 1-30, and I still don't understand how he could do a complete 180 in 1 chapter. I just want Haejin to get to the Amazon alone at this point. The story is bad but honestly readable. So weirdly captivating
