Those are more like technical differences. Of course I knew there would be of those, what I was comparing was the core of the premise, a "corruption" journey where MC suddenly gains a position of power in an academy, backed by misterious patrons that wish for a certain lewd agenda to be pushed into society, and MC acting as the agent to do it while imparting discipline and obedience to the girls. When you put it like that, they both sound so similar, right?
