Personally, I prefer to work out the path myself, like I would IRL. There are clues dropped in the story line, trails of bread crumbs. Talk to each of the girls whenever you have the opportunity (menu when you knock on their doors), some like to gossip. Level up their stats. Events don't happen in isolation in HH; but it's not grind-ey.
This is one the things that set this avn above others, IMHO. Excellent writing.
