I absolutely love this one. It has a great story and good comedy. Please say you have read it too, if not I highly recommend it!!

Summary
A regular college freshman Kim Jung Hyun and his room mate Kim Homo are polar opposites and friends. It's a story that deals with many sensitive topics with a dash of humor.
