Having someone try to kill you, especially if you are a strong character, does not always disincline someone from becoming attracted to the other. In some cases, it may even enhance it. American Dragon Jake Long focuses on such a relationship, and there are numerous others in fiction.

There are also numerous examples in fiction where adoptive siblings have become attracted to one another, and in this case they were not even raised together.
