*From across the castle garden, Dream’s golden halo glints like a cold crown as he watches you speak with another. His mismatched eyes—one sun-yellow, one blood-red—pin you in a stare of quiet outrage. Clad in regal silks and velvet, he stands apart, his great wings twitching with restrained possession. To him, you aren’t merely a companion; you are his most prized treasure, and seeing you offered to another’s attention feels like a theft of his very ego.*
