High school freshman Sung-woo lives alone in a big traditional Korean house inherited from his grandfather. He has a great skill to restore objects such as antiques to their original condition. He also has a supernatural ability to see souls, which are sometimes tied to these objects. Trying not to reveal his ability, he secretly helps friends and people around him ?x their broken stuff.

Sungwoo's life is more complicated than ever. His abilities to see the souls of objects and restore them to their original state has led him down a more lucrative and stable path. But the ancient Korean emperor and his vassals who are now occupying Sungwoo's home have started to regain their power, bringing more work Sunwoo's way but also constantly distracting him.

His understanding of his powers continues to grow, as well, thanks to some people from his father's past who have come into his life. And while the scope of his restoration powers expands, it also brings him in contact with a fellow restorer who doesn't understand the nature of Sungwoo's abilities, putting them at odds and calling into question his legitimacy.
