TikTok has launched a campaign to commemorate idol group CORTIS’s ‘GREENGREEN’ release, expanding the music consumption experience through an interactive structure that combines participation and rewards.
TikTok is running the global in-app campaign #GREENGREEN to mark the release of CORTIS’s second mini-album ‘GREENGREEN’. The campaign operates for two weeks from the 4th through the 17th, and anyone worldwide can participate via the dedicated campaign hub within the TikTok app.
The campaign is designed as an interactive structure that goes beyond listening, combining fan participation and rewards. Users can access the campaign hub by searching ‘CORTIS’ or related hashtags on TikTok, and experience the album more multidimensionally through various missions and content linked to the second mini-album ‘GREENGREEN’.
Global users who follow the official CORTIS TikTok account (@cortis_bighit), save the title track ‘REDRED’ in a music app, and create a video with the track can earn a profile frame available only during the campaign. Special missions that broaden the participation experience are also being run for users in Korea and Japan. Users in those countries can earn Heart Points for each mission completed, and if the accumulated points reach the target, CORTIS’s out-of-home advertisement will run in New York’s Times Square. By creating a structure in which fan participation leads to actual global exposure, the campaign increases immersion.
During the campaign, a ‘Listening Party’ will also run within the TikTok app. As users listen to the new release in the app, digital rewards will be revealed sequentially based on streaming counts, with various rewards provided at each tier, including group and member selfies.
On the 5th, CORTIS joined the Listening Party room in person and chatted with fans for about an hour. This allowed fans to go beyond simple content consumption and share a real-time connection with the artists in the same space. Communication with the artists will continue via live content. On the 8th at 11 p.m., TikTok plans to host an approximately one-hour exclusive vertical live session with CORTIS. The live will center on talk and games and can be viewed exclusively on TikTok.
Park Joo-young, Lead of Artist & Label Partnerships at TikTok Korea, said, “This campaign is characterized by expanding beyond simply listening to music into an experience of shaping the comeback together through completing missions and participating in content,” adding, “TikTok will continue to present new music experiences based on participatory content so that artists and fans can connect more deeply.”
CORTIS’s official TikTok account has surpassed 11.3 million followers and 740 million cumulative likes, and the group was recognized for its growth and buzz by winning the Global Rookie Award at the 2025 TikTok Awards.
Content using the second mini-album’s title track ‘REDRED’ has generated more than 60,000 videos per day on average since release, surpassing 900,000 as of the 5th. This exceeds the results of the ‘GO!’ challenge from the first mini-album, which was very popular on TikTok, demonstrating CORTIS’s growing influence within the TikTok community.
