Talented stars have been popular since high school. It is obvious that stars would graduate from art schools, such as Anyang Art High School, where Rain, Se7en, Park Han-byeol graduated from, and Kaywon Art High School, where Hwang Jeong-min, Kim Ji-soo, and Jo Seung-woo graduated from. But there are also many stars who come from regular schools.
Suhmoon High School is the most prominent. Some graduates are Lee Hyo-lee, Han Ji-min of "Yi San", super model/actress Lee Hwa-seon, actress Park So-eun, and singer Lee So-eun. Lee Hyo-lee was popular with the guy students for her beauty and Han Ji-min received casting requests. Lee Seung-yeon, Jeong Kyeong-soon, and Oh Jee-hye are also alumni. A rival to this school is Eunkwang High School nearby. There are rumors that there were many guys who came to see Lee Jin, Song Hye-kyo, and Han Hye-jin.
Some graduates of Whimoon High are Shinhwa member Kim Dong-wan, actors like Lee Dong-geon, Yoo Ji-tae, Park Yong-woo, Han Jae-seok, Koo Bon-seung, and talented singers like Lee Seung-hwan and Kim Dong-ryul. Kang Won-rae, Ji Sang-ryul, Koo Joon-yeob graduated from Kyunggi High, and Lee Dong-wook and Shinhwa member Shin Hye-sung graduated from Shinil High.
