Sexy Beach ZERO Story

In Sexy Beach ZERO you play a young Japanese men who arrives at a tropical island for vacation. During the game he tries to sway up to five different girls to start dating him and finally have sex with him. He does that by chatting, buying presents and going on dates with the girls. After a while he becomes more and more intimate with the girls which will allow him more and more intimite encounters and ultimately sex. So far as I understand there is no real ending to the game.
