TikTok debuts campaign for Cortis’ “GREENGREEN” release

TikTok has launched a new global campaign, “#GREENGREEN,” to celebrate the release of CORTIS’s second mini-album GREENGREEN. Running from May 4 to May 17, 2026, the campaign combines fan participation, interactive missions, and digital rewards to create a more immersive music experience inside the app.

Fans can access a dedicated campaign page by searching for CORTIS or related hashtags on TikTok. Users who follow the group’s official TikTok account, save the title track “REDRED” to their preferred music app, and create videos using the song can unlock a limited-edition profile frame.

TikTok is also introducing region-specific missions in Japan and South Korea. Fans in both countries can collect “Heart Points” through campaign activities, and once combined participation reaches a target milestone, a CORTIS outdoor advertisement will appear in Times Square, New York.

TikTok confirmed that CORTIS will continue engaging fans through exclusive TikTok LIVE sessions and real-time chats during the campaign period.
