<p>Not surprised it happened in Gangnam/Apgujeong-dong because it is also the richest area in Korea. It’s basically the Orange County of South Korea streets full of high-end stores(where Louis Vuitton bags cost more than the ones in the US by double/triple the price). Also the SAT’s are very very competitive over there so not surprised at all that tutors in Apgujeong-dong were the ones to have their hands on it -_-;;</p>
