    Summary

    An AU based on 'The Village', Rus knows he shouldn't be in the woods.

    (If you've never seen The Village, I think it would be enough to know that the villagers live in an isolated community surrounded by a forest. The woods are forbidden as Monsters are rumored to live in it and any shade of the color red is forbidden as it supposedly attracts them. Thus, Rus shouldn't be in the woods, but the forbidden can be oh, so attractive, can't it.)
