What the fuck is this VN??? It's turned into a marmalade h-scene fest with constant h-scenes back to back, except they're all routelets and it's still the common route!
The only thing I can think of is that they wanted to have a bunch of mini-routes for the heroines, Majikoi style, and they did all the h-scenes first, and then they realized they didn't have the time or budget to make mini-routes but the h-scenes were already done so they just kinda shoved them all in a row in the common route.
