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 fix their broken stuff.

Due to his abilities, Sung-woo soon finds himself surrounded by numerous ancient people/souls who help him fix things or solve difficult matters. And the more restoration projects and their related pieces of stuff he takes on, the more interesting his life becomes. But sudden visits from his missing father's graduate school advisor and a cute girl from an ancient Korean Kingdom will soon make the world know his unique skills...whether he wants it or not!
