The main character, Cho Isu, lived an ordinary but happy life. Five years ago, he suddenly loses his parents, and becomes a devastated man, as he struggles every day. When he was exhausted from the suffocating daily life, a portal opened in the room. A place he has never been to, a place he doesnt know what might be. A healing life to enjoy in a different world starting as a commoner and turning into a feudal lord.
