When Se-Yeong wakes from his coma, he realizes he’s lost everything. His parents are dead, having set themselves on fire to bring attention to how Se-Yeong was bullied by his rich peers in school. But from what he can gather, the whole lot of them—eight in total—have gone back to their normal lives without consequences thanks to having such rich and powerful parents. Filled with anger and regret, Se-Yeong locks himself up in the highest-up, rooftop apartment of the building his parents have left him, shutting himself away from the rest of the world. But strange things start happening; he finds a giant burning sword on the rooftop, and there’s a voice in his head, whispering to fight… Se-Yeong thought he’d lost everything, but looks like his revenge is just beginning now…
