This one is pretty useless to watch. You actually have to read the synopsis to get what's going on, as nothing of it is explained in the OVA itself. Shortly put, the story is about a girl which is somehow being blamed for the death of some dude. Therefore, she thinks of herself as a horrible person who should be with nobody and cuts all ties with her friends. In the end, they find her and they reunite. The End. It is unclear how that person died, or who that person was for that matter, how she is to blame for that, and how that person (orthe girl) is related to the other main character(s). Even for a single short OVA, it leaves a lot of open questions and vagueness. On top of that, it's quite boring.
