After her sister Della stabs her on coronation day, Wood Elf heir Leah is sent back in time—where Della steals her betrothal and arranges an orc assault, only for Leah to be rescued by a wanderer named Noah. When Leah publicly vows to marry him despite her clan's mockery, she doesn't know he is actually the Sun Elf court's revered pure-blood prince—whose hidden power ultimately elevates her to the elves' supreme throne.
