Honestly I think it’s cause they wanna either simplify things to make it easier or they wanna make it more digestible to readers by not including all the things people may not like. Specifically the darker romance stories, the author would change things to maybe make the romance feel less bad.
Though the changes in this story aren’t that bad since they aren’t really excluding any toxic parts. The only thing I noticed so far is that they changed the way that Raphael and klopp separated. In the novel, their feelings seemed more sincere to each other and actually felt sad- but they made it seem like they barely cared about each other in the manhwa scene. Their separation was changed and cut short.

yeah. I noticed that they cut short the separation and appeared less affected by it. Also the part where Aeroc came question Kloff about the break off. I don't remember the part where Aeroc tripped and kloff supported him from falling. Not sure, if i remembered that part wrongly.. He also seems more gentle with him compared to the novel.
Story starts to seems a little different towards the last few panels. Some of the things were also omitted.
