Nichkhun's older brother, Nichan, has become a hot topic amongst netizens lately after arriving in Korea on January 5th. Originally a VJ and MC in Thailand, Nichan is visiting Korea to 'teach' the�4minute ladies for�their new E Channel TV show, "4minute's Mr. Teacher." The reality show aims to prepare 4minute for their international advancement by teaching them different cultures and languages - the kicker lies in the fact that these tutors are hot, pretty boys from Thailand, Japan, Taiwan and many other locations. Nichan was chosen to be the group's Thai teacher. As he waits for his first broadcast on January 19th, Nichan commented, "I'll not only raise awareness about Thai culture, but reveal stories about my little brother, Nichkhun, as well."
