Maybe Undefeatable

Hyeol Yu is a third-rate warrior feared more for his menacing appearance than his actual skills. Branded by false rumors and endless misunderstandings, he has long been an outcast in the world of martial arts. But everything changes when Seolhwa, the woman he once vowed his life to, reappears before him as a true martial arts master. From that moment on, Hyeol is thrust into chaos, his name weaving its way through the ranks of warriors, sects, and factions. As his unwanted reputation spirals out of control, he is pulled into a conflict far greater than he ever imagined.
