What you decide to do (pleasure, sports, study and so on) raises your skill in that category. Every day when you wake up you get a chance to decide what you want to do in the morning, afternoon and night. True Love is not as good as Sentimental Graffiti, a popular Japanese dating sim that was never translated to English, but it comes quite close.
Your mission is to win the girls' hearts (naturally) before your last summer of freedom is over for good. You are a highschool boy looking for love and excitement.
One of the very few 'Hentai' games (Japanese adult titles) that I like, True Love is a Hentai adventure game with a difference.
