Jin was your average human being. He just has the ability to summon demons for some reason. Which is okay, as the demons he knows are quite nice and love his cooking. In return for dinner, they keep his apartment mouse free, which is a good deal in his opinion. If he one day accidentally summons one of the Princes of the Underworld, one of the Seven Sins, no one has to know...  

Namjoon was moving to a new apartment. It was larger and cheaper than his old apartment, a good deal. It was a good distance from the university where he would be finishing off his masters soon, and the studio where he worked wasn't too far either. A good deal. Really, the only thing that wasn't on the contract was his new roommate trapped in a mirror.
