Kim Ui-Gwon (김의권)

A 17-year-old named Kang Geon transfers to an elite high school attended only by the top 0.1% of South Korea. Trained since the age of five in North Korea as a human weapon and a genius secret agent, he’s given a mission to infiltrate South Korea’s high society and build connections. But making friends turns out to be the bigger challenge. Living under the guise of a family with his father, a hacker watched by nations, and his mother a legendary assassin, he navigates a spy-action drama in search of true happiness.

When Seyoung wakes from his coma, he realizes he’s lost everything. His parents are dead, having set themselves on fire to bring attention to how Seyoung 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, Seyoung 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… Seyoung thought he’d lost everything, but looks like his revenge is just beginning now…
