As what being told

retrieved from my childhood memory,
a story need a handsome protagonist and ugly antagonist,
and as usual it starts with;

once upon a time, there live;
a villager,
a sheep,
a wolf,

a bullet being released,
predictably it hit the wolf

in another life, there live;
a villager,
a sheep,
a wolf,

a bullet being released,
predictably it hit the sheep

tell me who is who,
the ugly protagonist and handsome antagonist!
