The Brothers of Apostasy

During his middle-school years, Seong-min lost his only remaining parent—his father—and grew up relying solely on himself. Years later, his older brother Han, who shares no blood relation with him, suddenly reappears and moves into his home. Through Han's arrival, Seong-min is forced to face hidden and uncomfortable truths about the father he idolized, causing the world he built around his father's memory to slowly crack and unravel.
