A binary star system is a celestial system in which two stars are bound by each other's gravity and revolve around the center of mass of the system. Two stars are gravitationally bound, born from the same source, and permanently entwined with each other.
They are each other's binary star system, one like the light of day and the other like the star of night. Some people say that they are twins, but it makes more sense to become each other's stars.
It's fun to write fanfiction, and everyone will have fun reading it. Please don't scold me if it's different from reality.
