I'm a Library NPC at Advanced Nurturing High School

Do you have any other sweet fanfiction recommendations? Ideally, the protagonist should be intelligent, and a harem is fine, but no harem stories. I feel most authors can't handle more than three characters, and the story often gets marginalized or out of character (OOC). #(Sweat)

Speaking of which, there are so many system-based protagonists in the "Real Classroom" fanfiction, isn't there a single one who wants to commit a school shooting? What about the biggest and most heinous event, or world conquest? Many of the protagonists in these fanfictions have built-in cheat codes that they can obviously do it, right?

Will the male protagonist have his own body?

Is it a harem or a single-woman story? I don't like single-woman stories, so I'm asking to be clear.

I doubt there will be a scene later where Hinata is kneeling on the ground, clutching a woman of unknown hair color, and humbly murmuring, "Onegay, give me back Mr. Ghost," 😭

Don't have eunuch teeth

After reading so many PvP fanfics, I feel that Ryuen's status in PvP is almost the same as Tifa in the 3D section. He's a man who combines highlights and laughs. I started laughing as soon as I saw him in the few books I've been following recently. #(Funny)

After reading the comments, I saw some arguments about how it's not good to have a harem, saying that the male lead and Hiyori share one body, and the other female leads are at a disadvantage in this regard, not having as many opportunities to develop relationships. I read a Madoka Magica fanfic that had a similar solution, except that in that one the male protagonist swapped bodies with different magical girl heroines. This one could be set up so that, after certain conditions are met, the male protagonist transfers into the corresponding heroine's body to solve the problem, gradually deepening his relationships with each heroine, slowly increasing his autonomy in transferring bodies, and finally introducing the issue of the male protagonist's body. Ultimately, the male protagonist's original body reappears, and the problem is perfectly solved. #(Funny) I think there's a lot to see in this aspect.

Two questions: Will the protagonist have his own body later on? Will it be a single female lead or multiple female leads? If he continues to share the same body with Shiina Hiyori, then I'd prefer a single female lead; otherwise, it's impossible to use Shiina's body to build a harem and engage in yuri, the vibe just doesn't feel right.

Sweet, sweet, sweet! Looking for a book similar to "One Body, Two Souls," where I can do anything.
