When Shelly first moved to Korea, he shadowed her as she was introduced to the class and witnessed his precious grand-baby kiss a good for nothing hellion, Jay. He recruited Mr. Nam to be their homeroom teacher in order to keep an eye out for the two teens. When Jay, Minu, and Dom were suspended, he took some time to train them and prepare them for the up coming preliminaries. He reveal after their suspension, that he was one of the organisers of the competition. He used to train both Mahon Jo and Sungho Choi when they cycles internationally.
