Destined Mate
The 'lifelong partner' who is destined from birth.
Two people bound as destined mates are inevitably drawn to each other. The moment of realization varies for each person, and even if one person realizes they are destined mates, the other may not.
However, being destined mates does not guarantee they will end up together.
