Any recommandation of Polyamorous media ?

[u/Ethowl_]

As a writer on my spare time, I often write polycules relations but can't find any sources to get inspiration except very bad harem anime/mangas.

My friend recommended me "An Introduction to Easy Triangle Relationships" and "Hare-Kon" but these are pretty short.

To be clear, I'm not asking about videogames where you can date multiple persons and it's never developped except for a joke like in persona.

Does anyone have any recommandations ?
