K-pop is popular around the world nowadays, but before BTS and Blackpink, many people's first introduction to the music came through Psy.
A young boy dressed up as Psy also showed off his slick dance moves and endeared viewers, and Koreaboo recently reported that the child — Hwang Min-woo — is now 19, and a performer himself. The school's alma mater includes notable K-pop stars such as idol-turned-actress Suzy, BTS' Jungkook, Exo's Kai, Oh My Girl's Arin and Hyunjin from Stray Kids.
