This is perhaps the most emotional OAV I've ever watched! The funny thing is, most of the story takes place in space, so the main characters never kiss, or any of that lovey dovey stuff. It takes romance to a whole other level. It's like the longest long distant relationship ever. I cried alot, really. It was just so beautifull. The best 25 minute OAV in anime history that goes deeper that full lenght serieses.
