Choi Siwon considered himself to be a humble, patient, understanding and tolerant man. Shortly after graduating from the University of Seoul, he moved to America.   After eight months of constant vigilance, determination, and prayer, he'd quickly found a job he loved, the perfect living space, and at the tender age of twenty-five, he was compelled to admit that he was content with his life.   Then he'd had to get a roommate.
