a while back some1 posted an anime on here. It was zombie themed and i cant remember the name, they didnt have many episodes out. the first episode showed them all at a school and there was a guy dating a girl and another guy who previously liked that girl and she had told him when they were kids that she was going to marry him when they were older. The guy dating the girl got bit and the other guy had to kill him.
hope thats enough for someone to realize what anime it was and tell me. thanks
