Perhaps Invincible

Yu Hyeol is a third-rate warrior whose fearsome appearance earns him the nickname “The Star of the Dark Arts” and leaves him beset by rumors and misunderstandings. His life changes when Seolhwa, the woman he once promised to build a future with, returns as a formidable martial arts master rather than the gentle figure he remembers. Their reunion draws Yu Hyeol into the affairs of countless warriors, further inflaming his already notorious reputation. The Murim Alliance, the Demon Cult, and even the royal court begin taking notice of him. Yu Hyeol insists that everything is a misunderstanding, but it remains to be seen whether he can persuade the world—or accidentally become the legend he never set out to be.
