My Tomorrow, Your Yesterday

Takatoshi Minamiyama majors in art at an university in Kyoto. On the train to the school, he sees Emi Fukuju and falls in love with her at first sight. Gathering up all his courage, he speaks to her. They begin to date and enjoy happy days together, but Emi reveals her secret to him.
The plot's really cool, but I was wondering if they'd follow their "route" if they didn't tell the other what to say in the future or what will they do next day.
Also, a little fail in the timeline: how do they live in both worlds but not know things from the other world? Like Emi came from that other world with all her memories, she also knew she is gonna disappear (or what) midnight, but she didn't know anything about her future (Takatoshi's past). (I can't really explain this, but it's bugging me so much. xD)
