This does look promising, curious before going in blind, does the vision you have for this game include romancing the MC's? Dates for events, having a committed route if someone has a favorite, that kind of thing?
There's already a few date events in the game, though they arent explicitly marked, they're just part of the natural progression.
There isn't plans for a dedicated route system, as I do not enjoy that type of gameplay, I hate having missable content and locked off scenes so it probably won't be something I will add.
