The group CORTIS is organizing a global campaign “#Greengreen” in collaboration with TikTok to commemorate the release of its second mini-album “GREENGREEN”.

This event takes place for two weeks, from May 4 to 17, and it is possible to participate via a dedicated campaign hub within the application.
This campaign was designed according to a method combining fan participation and rewards. Users can access the hub by searching for CORTIS or associated hashtags on TikTok, and they will be able to discover various contents through missions related to the album.
By following the official TikTok account, saving the title song “Redred” on a music application, and then creating a video with said sound source, it is possible to obtain a limited-time profile frame. A special mission expanding the scope of participation is also managed for users in Korea and Japan. When users in these countries complete the missions, they receive heart points, and if the points reach a target value, an outdoor advertisement for CORTIS will be displayed in Times Square in New York.
A “Listening Party” is also organized during the campaign period. By listening to these tracks on the application, digital rewards will be revealed sequentially according to playback figures, and photos of the group and the members will be provided in stages.
Last May 5, the members of CORTIS participated directly in the “Listening Party” room to hold a real-time chat with fans for about one hour. Communication also continues with live content. Next May 8 at 11 p.m. KST, an exclusive live broadcast on TikTok, consisting of discussions and games, is expected to be aired for about one hour.

Park Ju Young, Lead Artist & Label Partnership at TikTok Korea, stated:
“This campaign is characterized by the extension of the fan experience, which does not stop at listening to music, but consists of creating the comeback together through the completion of missions and participation in content. TikTok plans to continue presenting new musical experiences based on participatory content so that artists and fans can be connected more deeply in the future.”
Currently, the official TikTok account of CORTIS has exceeded 11.3 million followers and 740 million cumulative “likes.” They won the Global Rookie award at the “2025 TikTok Awards”. Contents using the current title song “Redred” generate an average of more than 60,000 videos per day since their publication, and have exceeded 900,000 cases as of the 5th. This is a figure that surpasses the record of “Go!”, a song from their first mini-album that had previously attracted attention.
