What if

Snape never got the chance to become the hateful greasy git we know him to be? What if two people entered his life early on and prevented him from becoming one? A small 6 y.o. child, a spitting image of his school nemesis, and a young beautiful woman, a spitting image of his lost love. Mix of Severitus and Teacher/Student romance. Rated M for adult themes. Warning for parental CP.
