If you give both options that would be great. That way everyone can play the game any way they want. For me it's all of them.
That is absolutely what I intend to do. Only a couple of highly polarizing girls are being given forks in their paths (Cecilia is one of them), but almost all of them will be accessible and romanceable while not disturbing the main story. Those who want everything should still be able to see everything. Those who are more picky will be able to skip the ones they don't like.
I gotchu bro.
