The group CORTIS showcased a highly polished performance and candid talk on KBS2's 'The Seasons - Sung Si-kyung's Eardrum Boyfriend'.

Appearing on the May 5 broadcast of 'The Seasons - Sung Si-kyung's Eardrum Boyfriend', CORTIS opened the stage with a band arrangement version of their debut album's title track, 'What You Want'. They followed up with performances of the b-side track 'Blue Lips' and the title track 'REDRED' from their 2nd mini album, drawing enthusiastic responses from the audience.

They also captured attention during the talk segment. The members exuded a friendly charm as they shared their unique team identity and the behind-the-scenes story of their track 'YOUNGCREATORCREW', which has recently become a viral catchphrase. In particular, recorded as the youngest guests to appear on the show that day, CORTIS left a lighthearted video message for their future selves 10 years from now, displaying the bold audacity typical of promising rookies.

Such impressive feats are extending to their digital and physical album chart performances. CORTIS's 2nd mini album 'GREENGREEN' and its title track 'REDRED' are achieving consistent success on both domestic and international charts. 'REDRED' ranked No. 1 on the Spotify Korea Weekly Chart for five consecutive weeks and No. 104 on the Global Weekly Chart, while also making its name on the Billboard Japan First Half 'Heatseekers Songs' chart. The 2nd mini album also achieved the milestone of entering the US Billboard 200 chart for three consecutive weeks and topped the Hanteo Chart's monthly album chart for May.

Meanwhile, CORTIS is scheduled to continue their activities with an appearance at the '2026 Weverse Con Festival', which will be held at Seoul Olympic Park on the upcoming 7th.
