In case anyone's still looking, you can unlock the brown haired girl's route by going down and to the right as soon as the game starts. Some other things I've noted are that you can buy food at the convenience store and give them to the girls to quickly increase their affection. Then you just have to do things like taking them on dates (the door symbol at the bottom when talking to them), having them try on clothes (shirt symbol) that you buy at the adult shop, or doing ecchi things (heart symbol). You have to do the same sexual acts multiple times to unlock variations or sometimes other sexual acts, and you can track how many times you need to do them by opening the scene replayer and clicking on each scene. The selected scene will have white and gray numbers; the gray numbers are the ones you have to do to continue.
