I'm not sure which specific 'Sale Pelletier Love Story' you are referring to. There could be many people named Sale and Pelletier. Maybe it's a story within a particular community, family or a work of fiction that I'm not familiar with.

Jamie Sale and David Pelletier's love story is one that developed in the world of figure skating. As they practiced and competed side by side, they got to know each other on a very deep level. They understood the sacrifices and joys of the sport like no one else could for each other. Their relationship was a source of strength for them in the highly competitive figure skating arena, and they became not only partners in skating but also in life.
