CORTIS's 'REDRED' has returned to the top of a music show six months after its release. The group, composed of Martin, James, Juhun, Sunghyun, and Gunho, has proven both a strong fandom and mainstream appeal with 'REDRED,' the title track of their second mini album, continuing a long-running streak of success.

No. 1 Without Broadcast Points... A Reverse Run Built on Streaming, Album Sales, and Fandom

Released in April, 'REDRED' took first place on the first week of October's 'K-Chart' announced on the official website of KBS2's 'Music Bank.' With this result, CORTIS's total number of wins on major domestic music shows has risen to 12.

What draws attention is the reason behind the win. Although there were no broadcast appearance points in this tally, the group reached the top by securing high scores in the remaining categories, including digital streaming, album sales, social media, and fan voting. In other words, steady consumption of the song and the cohesion of the fandom, even after official promotional activities had ended, translated into this result.

A 'Grand Slam' and 22 Weeks on Billboard... Global Success Continues

CORTIS previously achieved the so-called 'Grand Slam' by topping all five major domestic music shows. With this additional 'Music Bank' win, 'REDRED' is being evaluated as extending beyond short-term popularity into long-term success.

'REDRED' has established itself as a signature song, combining highly addictive sound and performance with the members' co-writing. The members divided the elements they guard against as 'RED' and the direction they pursue as 'GREEN,' embedding this message in the song.

The song's presence continues on global charts as well. As of the Billboard charts dated October 3, 'REDRED' ranked 198th on the 'Global 200' and 100th on 'Global (Excl. US),' extending its streak of entries to 22 consecutive weeks on each. With a single song maintaining results simultaneously on domestic music shows and global charts for several months, 'REDRED' is regarded as CORTIS's long-running hit of the year.

Starting at 11th in the October Netizens' Awards... Global Fan Sentiment Is Another Point to Watch

The fandom's movement is also notable in the October Netizens' Awards. As of the afternoon of the 7th, CORTIS sits in 11th place in the Best Group category. Attention is focused on what kind of trend the fan sentiment backing the song's long-running music show success will create in the awards rankings going forward.

Meanwhile, in the Globe Netizens' Awards, which offers a glimpse into global fan sentiment, no votes for CORTIS have been cast yet. As the group expands its reach both domestically and internationally, whether global fans' movements will begin in earnest is expected to be another point of interest.

F1 Singapore Grand Prix 2026 Stage on October 9

CORTIS's scope of activity is also widening. The group has been invited as a K-pop artist to the 'Formula One (F1) Singapore Grand Prix 2026' on October 9, where they are scheduled to perform a solo show of about 50 minutes on the main stage at the Marina Bay Street Circuit in Singapore.

With a return to No. 1 on domestic music shows, long-term chart entries globally, and now a major overseas stage ahead, attention is focused on how far CORTIS's upward momentum will go. The fandom's showing in the October Netizens' Awards race, which started at 11th place in the Best Group category, and in the Globe Netizens' Awards, where votes have yet to move, will also be worth watching.
