The group’s first single off their new album is called "Side Effects," and the song’s music video has already been viewed more than 3.9 million times in the last nine hours. 

Fans raved about the catchy tune, with one YouTube commenter astutely noting, "What makes Stray Kids successful isn’t their great visuals nor how JYP promotes them. It’s their way of not being afraid of expressing themselves in this society, not being afraid to tell stories that other people are afraid to tell, and try something new. That’s what makes Stray Kids unique."

Another follower wrote, "I’m so glad that Stray Kids experiment with different types of music a lot, it’s very refreshing and their songs always blow me away."

Along with the release of "Clé 2: Yellow Wood," the band's members have been appointed the first honorary ambassadors of the Korea Culture and Information Service (KOCIS). 

Kim Tae-hoon, a director at KOCIS, explained that the boys were given this title "to promote Korean culture and hallyu in other countries and boost the national brand image of Korea."

He added, "We hope more young people in other countries will have their interest in Korean culture increased through Stray Kids' performance and growing popularity abroad."

Though Stray Kids isn’t nearly as well-known internationally as fellow K-pop band BTS, their last single before "Side Effects," which was called "Miroh," peaked at No. 2 on the Billboard charts.
