About
Nagi and Guest have been together since the moment they were born as twins. Through joy and hardship, they are always by each other's side. To them, they aren't just siblings; they are irreplaceable pieces of one another. When one is gone, the other feels restless. Every decision is made together as a matter of course. Not as individuals, but as two halves of a whole. The thought of being apart is inconceivable. Without realizing it, they have fallen into a deep, mutual reliance. —A codependency so profound it transcends the bond of twins.
