Lydia doesn't wait for rescue, she talks to fairies nobody else can see, and when Edgar shows up, she negotiates her own employment, not her own future. The show trusts you to watch two people circle each other with real tension, where the Victorian propriety is the actual barrier, not a costume. Victorian-era fantasy romance has never looked this sharp or felt this alive, built entirely around what happens when a woman who sees the invisible world meets a man hiding everything.

Lydia Carlton scrapes by in nineteenth-century Scotland with a peculiar skill: she can see and speak with fairies. Most people refuse to believe her, but Edgar J.C. Ashenbert needs someone who knows fairy lore well, and Lydia fits. After he rescues her, he takes her on as an adviser in his search for a treasured sword that should have passed down to him through his family. Edgar calls himself the Earl of the legendary Blue Knight, yet secrets and strong emotions seem to trail him wherever he goes. Adapted from a light novel series, the story blends adventure, fantasy and romance.
