Thanks in advance.. I remember the story revolved around a producer/singer who is hiding the fact that he is gay was trying to do something new. He is part of an Idol tv show where he meets the up and coming rapper and becomes the mentor of the rapper on the show. There's something along the lines of the producer won't sleep with the rapper unless he wins. I believe the original lang. is Korean. The rapper is a smart college student and his "posse" is run by a older Christian cross-wearing rapper.
