Hypno-harem

The protagonist gets a cheat ability from his future descendant. How does he use it?

To make a small(?) harem.

Guys, due to personal reasons I will not be able to update the novel. So it is sort of going on a hiatus. Sorry for doing this so early in the book. I will be able to continue writing in a few months. Don't worry, I am thinking of new ideas for chapters everyday. This novel will not be a short one.
Thank you for reading my novel.

By the way, I started writing this novel because of my own fantasies. Most of the other web-novels I read on this genre are somewhat one-dimensional, as in they keep doing the same stuff but with different women, like a mature loli or a gym trainer, or maybe a teacher, or a nurse or something like that. The idea behind the hypnosis is the same thing. I got bored of that so I decided to write my own novel with more ideas.

I am not calling out the authors with such ideas. I just thought that more ideas is better, so I am writing this novel.

Only 18+. All the characters are fake and not real, by the way. This novel does not seek to offend anyone. This is not a fan-fiction by the way. I might do that in my next novel though. Like hypnosis in Naruto or BnHA or something like that.
