Check the walkthrough in the OP. The handholder pdf. It was posted by Stiglet.Maybe i repeat myself but the fact, that the game has hidden scores (not game paths or bools), makes it kinda hard to get the harem ending. I wish Devs would realize, that communicating fundamental game mechanics to the players makes the game more satisfactory. I want to Fap to my perfect ending, not the one i ' accidentally' got. Well 'open dev console' it is...
It details what choices you need to make to get to a certain ending.
