On April 1 , 2018 , Red Velvet performed the song along with " Red Flavor " in Pyongyang at the East Pyongyang Grand Theatre to an audience that included Kim Jong-un during a concert billed as " Spring is Coming " , intended as part of a wider diplomatic initiative between South Korea and North Korea . This made them only the fifth idol group to ever perform in North Korea and the first artist from SM Entertainment in fifteen years since Shinhwa . The group also performed a half-Korean , half-English version of the song at a fan meeting in Chicago in April 2018 , months before the release of its official English version in August
