When Brave Hero Xia Li returns to Earth after three years slaying dragons on the Azure Continent, he expects a quiet reunion. Instead, he discovers an unexpected passenger in his magical baggage: Lucia Sivana, the legendary Silver Dragon Queen—now stripped of her powers and her memories, transformed into a vulnerable teenage girl. Trapped in an amnesiac daze, Lucia mistakes mundane Earth inventions for advanced magic. A flashlight becomes "holy light superior to dragon technology." Television is simply "moving magic paintings." A rice cooker? Nothing short of humanity's greatest achievement. Her endless appetite and total lack of common sense leave Xia Li exasperated, yet unable to abandon the very enemy he once vowed to destroy. Taking her in under the guise of roommates—both to avoid legal disaster and to monitor her dragon instincts—Xia Li navigates the chaos of post-graduate job hunting and freelance writing while serving as an unwilling guide to modern society. Between explaining why shiny packaging isn't defensive magic and preventing her from hoarding "treasure," their relationship shifts dramatically. What began as careful caretaking transforms into genuine friendship, then blurs into something neither anticipated. Can Xia Li teach a dragon the rules of Earth before her instincts—and her growing feelings—complicate everything? And what happens when their dangerous past finally resurfaces?
