items that could change the story of some characters were discarded like the seed from Plerion, his Authority -Demon Hunter- was only showed in 1 chapter and then it no longer appeared, extra towers, the memory (existencial) wipe without previous warning, Athena, the sub-worlds, e.t.c

his novel was so tr*sh that even the AI could re-write for better, and he allowed the AI to do!

In the story we get told that the higher dimension you live in the more stable the world is and the less stuff like magic, superpowers or gods exist. Our world being of the highest dimension is the most stable one. However a being in a lower dimension wanted to create a universe but their unable to create a new world on their own instead they need to borrow the ideas or worlds created by ppl in our world. On top of that they also need the souls of that person to create this world and act as an anchor that makes this new world stable. So in accepting that this being in a lower dimension was allowed to use and write his story however he wanted he somehow agreed to having his story turn real and become a part of it.

At this point it's kinda weird since it's explained that creatures of a higher dimension are overall much more powerful but somehow by saying yes the MC was kidnapped and then used as a battery to create a new world. It's also explained that if he ever dies during the story the world will cease to exist as well since he's the creator and what keeps the world and everyone in it, all the dimensions connected to it and so on alive and running.

Later on it's also explained that once the story finishes his soul will truly fuze with this world and it will become stable by pretty much taking all his powers as a higher dimensional being. Which will also result in him losing all his powers and becoming a normal mortal.

To me this part felt kinda convoluted because the story sets it up as he's the creator god and pretty much all powerful in this world but because he gave away his story writing rights to the "co-author" who's from a lower dimension then him. He somehow only had access to a fraction of the powers he should have and eventually even lost that and everything he had gained through out the novel. Almost everyone he knows also loses all their memories of him because of him losing his "self" so to speak-

Pretty much the MC get's a girlfriend fairly early on I would say but he was forced to kill her brother or the brother would have turned into a demon that would have killed a lot of ppl. When she eventually learns of this she can't forgive him and even if she loves him above all else she can't be together with him. In the end however she get's an item that let's her wish for anything and she makes a wish to return to the past so she can save her brother and be with the MC, which would create a separate dimension where the story starts all over but with her getting the knowledge of what was to come.

The main love interest is also introduced fairly early on then she and the MC pretty much falls for each other but it takes quite some time for them to become a couple that lasts to the end, her being one of the few who remembers him in the end.

Why I call it a maybe harem is that there are two other girls who loves the MC as well from early on and they also remember the MC and seemingly lives with him or visits him a lot in the ending but it's never explained if he ends up with them as well or they stay as friends. One of them is even the mother of his daughter. The daughter is born from a seed that was given a drop of blood from the mother and infused with the MC's power which gave birth to a witch so no hanky panky between them.
