Walking away has always been an option. No one forced you to read.
Just because you don't like something doesn't mean it shouldn't exist. This story is great and frankly more interesting that Full Volume in terms of creativity in writing. It's revisiting the very popular concept of reincarnation in a new way. Which is always a hard thing to do.

You know what's funny in all this? It IS the same author. It's just that the information doesn't mention the names in Korean. If you go to official websites it IS the same.
So no there's no "reason" why Full volume has a "different author than artist" I don't even know where you got this from. It's just that you don't like it and should walk away instead of insulting the author's work just because it's not the same trajectory as the other story you like.
It's basically the same phenomenon as BJ Alex and Jinx: y'all don't like the toxic story and should learn to walk away, because from a strict writing point of view, with narrative scheme and evolution of plot, character building and world building there's nothing wrong, there's just sex scenes in between.
So it's genuinely just you. Stop trying to objectify your criticism that is based on nothing objective. It's just you, so walk away.
Enough time has passed, I can confidently say this is buns. There’s a reason full volume has a different author than artist. I think this artist should stick to just drawing
