I prefer the MC is a male.
I don't care about the romance, but, PLEASE!
NO YAOI! NO YURI! NO HAREM! NO REVERSE HAREM!
Just that.

You could give mine a read. Just finished the first book and will be editing it now. Leave some brutal feedback if you want ;)

Doesn’t have any of those things you mentioned.

What I have is my second novel, just Accepted here today, "Worst World Renewal", that features "fixing the world's problems" if that's what you mean. Of course, if you literally meant, "fixing the geosphere of a world/planet" then my story is different entirely. First, define what you mean, "fixing worlds"....

My novel might fit the bill, except it does hint at potential harem settings -- or rather, I use the potential of being a harem setting in, what do they call it, a "Deconstruction of the Harem Setting" I might say. In fact, one character asking the main character "What are you doing, starting a harem?" is one attempt to rather deconstruct this scenario, as slightly as possible, while leaving in the potential for harem. (It's an Isekai story where the royals and elite social class allow polygamy, but the MC is more conservative-minded, but through the starting adventure, he gets put together with the princess and her maid, because of course he would. Hilarity might ensure, but adventure and chaos CERTAINLY will.

No yaoi or yuri in any of my stories, ever ... well, yet, anyway. One almost-yuri in another story, not this one.

Fixing Worlds:
Fixing various problem in a world, or worlds, that potentially influencing the universe, or multiverse, in bad way. 
Examples, eliminating an dangerous energy/element/power in a world that not yet ready to accept it; 
Fixing a currents of energy/element/power in a world that got disarray because some circumtances, like a ritual that gone wrong, or an irresponsibly exploitation with war as the reason;
Eliminating peoples that got seriously dangerous enlightement;
and such.

I find it curious that whenever a non-native-English-speaking-person says so, they are far more likely to be speaking/typing in almost *perfect* English -- and performing the task in a far more correct manner than most native-English-speaking-persons. So, thank you for being so competent in this language as well as your native language; and thank you again for your humble honesty.

Because, I just using feeling when I wrote it, and although I felt it was good, my english exam score was barely passing the mark T_T.
