First, create an interesting main character. He should have a unique personality, maybe he's shy or really outgoing. Then, develop a diverse group of male characters for the harem. Each should have different traits like one could be the jock type, another the nerdy type. Also, focus on building good relationships. Don't just make it all about romance at once. Let the friendships develop first.
Well, 'Given' can also be considered in a way. While it mainly focuses on the main couple's relationship, there are other male characters around who have strong emotional bonds with the protagonists, creating a sort of harem - like dynamic. Also, in some shounen - ai manga that are not as well - known globally, like 'Koisuru Boukun', there are multiple male characters vying for the attention of one main male character which is a characteristic of a harem story.
The theme of self - discovery is also quite prevalent. As the main character navigates through the relationships in the harem, they often learn more about their own identity, desires, and what they truly want in a partner. For example, they might realize that they are attracted to certain personality traits more than others through their interactions. It's a journey of understanding oneself in the context of multiple potential relationships.
One common trope is the central male character having a group of diverse male suitors. Each suitor might have a distinct personality, like the brooding one, the cheerful one. Another is the exploration of complex relationships within the harem, with elements of jealousy and friendship co - existing.
Some popular themes include friendship among the members of the harem. Even though they are all interested in the same person, they often develop deep bonds with each other. Romance and courtship are also big themes. Each member of the harem tries to win the heart of the main character in their own unique way. And power dynamics can be a theme too, as different characters may have different levels of influence or social standing which affects how they interact in the harem situation.

Since we don't know the specific 'nerd's harem gay story', the main characters could be a diverse group. There might be the titular nerd, who perhaps is intelligent but socially awkward. And then there could be other characters in his harem, like a jock - type who is starting to see the nerd in a new light, or an artsy guy who is attracted to the nerd's unique qualities. But again, this is pure speculation without more knowledge of the story.
Sadly, it's a rather niche genre and not as mainstream, so there isn't a long list of well - known 'gay harem novel' authors.

Some authors who write diverse LGBTQ+ stories might also incorporate elements of the harem into their works.
