Mortal enemies?

The Kaulitz and Salvatierra families have been rivals for generations. For years, they have competed for power, territory, and influence, accumulating betrayals and losses that have turned the rivalry into a deep-seated hatred.
Tom and Leah belong to opposite sides of that war, but they have never met nor had direct contact. Each has grown up hearing stories about the other surname and learning to consider them the enemy.
Everything changes when Leah orders an attack on one of the Kaulitz properties. The attack causes severe damage and directly affects Tom's family.
When Tom discovers that Leah Salvatierra was the one who gave the order, he decides that the rivalry between their families is no longer enough.
Now, he wants to find her.
He doesn't know what Leah is actually like, how she thinks, or what kind of person she is. He only knows her name and the family she belongs to.
Leah doesn't know what Tom is like either. To her, he is simply the Kaulitz heir and, therefore, one of her mortal enemies.
