Novel Idea!

Hi guys this is my novel Idea and I hope someone picks it up because I don't have the time or brain cells to actually write a novel.

The main tags I would like to see with this are weak to strong, regressors, HighIQ, Comedy, Harem, and R18.

Honestly, the tags are up to the author and their own writing style those were just my ideas.

The main idea behind this novel is that there is an apocalypse external like aliens or internal like zombies, an apocalypse where everyone gets a system, awakens a power, or something else like that.

Then our MC is the person that survived the longest out of everyone on earth. Then after he dies, he regresses but he doesn't realize everyone regressed with the memories of their past life.

No one is allowed to talk about how they regressed (world law or something like that) and for the first part of the novel, everyone thinks other people are finding treasures because of the butterfly effect.

Our MC figures this out earlier than others and starts to target more difficult opportunities that other people might not target yet so he can get ahead.

If you're going for the harem path maybe have backstories with some ladies from before the regression where he saved their lives, but they die in the end so none of the ladies really know each other. If you make some yandere I will love, you for life lol.

But in all seriousness, a yandere lover or two would be an interesting idea to add.

If you're going for the singular female lead maybe a childhood friend that died and broke the MC, or maybe a super powerful person not from the earth that didn't keep her memories and he must find her and make her fall in love with him again.

And a non-love lifestyle maybe make him a dense protagonist with many female friends or a mentally strong MC that doesn't need no women (lol).

Honestly, that's kind of my idea I have realized many novels are the same but written differently and I haven't seen a novel like this before. Maybe because it would be difficult to write something like this Idk.

I hope someone decides to write a novel like this, if you do I will try and read it until you stop writing it (if it's not too bad lol).
