Does /a/ prefer harems where the members are friendly with one another or are in active competition with each other?
Even if it's rape in the name of dominance?
Harem members being best friends is the only way to a harmonious end.
Are there any harem series where there isn't a "main girl"? It'd be bad for marketing purposes but having a single main girl at all seems sorta unconducive to the whole idea and just turns it into a standard romance with some side girls who pop up here and there, most of the time.
