Mmm it depends on how you feel to write the harem, if you have enough creativity you can try to create a story for each girl to give more content to the story. My advice would be to use girls who already know your story so you have a better starting point to write from, thus avoiding some writer's block. I would say that hermione, luna, astoria, daphne, tonks, fleur, they are girls who already have a story which would be easy for you to fit into your story, to make better writing and congruence than a girl without a story like cho , or the twins. My choice would be hermione, tonks, astoria and luna. (instead of an OC you can give Astoria the personality you want because not much is known about her personality, but she already has a way to relate her to red, either through her house or by having red heal her )
hay varias chicas que no usan como (las gemelas , cho chang , entre otras) , donde puedes usar para conectar y poder sacar mas contenido , digo por ejemplo si va de viaje a la familia de las gemelas . puede poner algo nuevo y salir beneficiado xD(aunque para el mundo de harry potter maximo de chicas serian : 8 ) , puede hacer que cada chica sean buenas en algunas materias como , mejor uso de pociones , mejor uso de hechizos , entre otras cosas xD.(no necesariamente tener mas de 5 chicas lo hace algo malo ).
