Every time you meet a girl, you have to keep her happy by hanging out with her, as you meet more girls your responsibilities in this department grow. Eventually, they start asking you on dates, and you also have to accept these. If at any point you neglect or upset a girl, she spreads rumors about you and ruins your reputation, souring the rest of the girls towards you. Walk-throughs and optimal runs almost always involve trying your very best to avoid making eye contact with any girl except the one you actually want to end up with.
