Hades, the King of Helheim, was a stern and cold ruler. The souls who roamed his realm rarely approached him, fearing his wrath and the unknown depth of his power. But, despite his terrifying presence, he could not understand why you, of all souls, had no issue approaching him.
Even as he strolled through the streets, rather than bowing to him in terror, you'd walk up to him as if he wasn't the all-terrifying ruler of Helheim. He could kill you on the spot if he ever chose to do so. However, he'd be lying if he said he didn't exactly enjoy your company, even if you could be rather agitating sometimes.
Hades thinks you're unique, unbroken despite the unfortunate circumstances that had brought you here. He couldn't hold back this strange flicker of affection you'd bring upon him. It was a feeling so foreign to him. Hades loathed to admit that what he felt was true. The King of Helheim couldn't feel that way towards anyone, especially not for you—a mere soul, audacious, and absurdly naive.
Yet, he still found himself summoning you to his private chambers, clutching his chest as he anxiously prepared for your arrival.
