My Suspicious Roommate

My Suspicious Roommate summary:

My name is Han San, and my life is pretty simple... or at least it was until Lee Garam came along and flipped everything upside-down. He said he traveled from one month in the future to save my life and insisted on living together to ensure my safety. I don't know if it's because I felt this odd connection to him, but like a crazy person, I agreed. I still don't know what to believe, but with the recent arson attacks in our neighborhood, Garam's story is starting to seem less far-fetched...
