Ok, so the gist of the story, is this boy who is bullied relentlessly, at home, at school, at work. He has no peace save for the few minutes he can steal here and there in his hidden spot in the forest.
He decides to take his own life. But before he does he decides to attend the 'party' of the year. Not because he is popular, but because he wants one taste of happiness before its all over.
Of course, he begins to enjoy himself, but is soon singled out by the bullies who crash the party and chase him into the basement.
