Maybe the story could be about how Leah's imprint on Edward changes her. She could become more determined to bridge the gap between werewolves and vampires. For example, she might try to convince the other werewolves that not all vampires are bad because of her newfound connection to Edward. And Edward, in turn, might start to see the werewolves in a different light. It could also involve them facing external threats together, which forces them to rely on each other.
In some fanfictions, Edward and Leah might be involved in a mystery together. For example, there could be a series of strange events in Forks that seem to be related to both vampires and werewolves. They are forced to put aside their differences and join forces to solve the mystery. As they work closely, they start to see each other in a new light, and a romantic relationship might develop in the process.

Leah, in the Bible story, was Laban's daughter. Jacob worked for Laban for seven years to marry Rachel, but Laban deceived him and gave Leah first. Leah was in a rather difficult situation. She had to compete for Jacob's love with her sister. Despite this, she played an important role in the family and the continuation of Jacob's lineage as she gave birth to several sons.
Leah was one of the wives of Jacob in the Bible. She was the older daughter of Laban. Leah was not as favored by Jacob as her sister Rachel in the beginning. But she was very fertile and gave birth to many sons for Jacob, which was highly regarded in that patriarchal society.
