(Hacker/thief kinda AU) Sungjong was that normal 20-something year old out of college that everyone had in their neighborhood at least once in their life. He was the person who'd take care of your pets if you went away, the oppa the children would swarm around for candy, and the sweetheart on the block. 

But Sungjong also was an orphan who's life was composed of an intricate spiderweb of lies. 

And Sungjong also happens to be the only person in the world who solved INFINITIZE:100609, the world's hardest cryptography and virtual puzzle created by an anonymous group to search for "highly intelligent individuals". And now they want him.
