>Satsuki's competition with Mai was about Mai, not Renako. Saying that they "competed over Renako" is true as a technicality but the relationship between Satsuki, Mai, and Renako is still fundamentally different from harem dynamics.
They're competing over which one of them will marry Renako. Even if it was just to one up each other, the 2 of them considered datig Renako a prize of their competition.
