Boy band Cortis (Martin, James, Juhun, Seonghyun, Geonho) appeared on MBC FM4U's Noon's Hope with Kim Shin-young on May 5 to introduce GREENGREEN, their second mini-album, which was released the day before.
On their first radio appearance since the comeback, the members said the album contrasts RED — the things they avoid — with GREEN — what they've done and what they want to pursue. \"We filled the record with songs rooted in our daily lives and worked on them imagining the stage,\" they said.
When DJ Kim Shin-young mentioned that the album sold a million copies on its first day, the members responded, \"We're hearing that for the first time. We're honored and grateful,\" and visibly beamed.
Cortis explained they had strong confidence in the lead single, which is why they released \"REDRED\" ahead of the album. \"We built the beat first, and the RED concept followed,\" they said. \"We revised the melody roughly 300 times,\" they added, giving a glimpse into the song's long development. Using the song's RED metaphor, they also shared everyday stories about the things the group steers clear of.
The members also recounted a congratulatory performance they gave at a luncheon for South Korea's Olympic team held at the Blue House in February for athletes competing at the 25th Milan–Cortina d'Ampezzo Winter Olympics. The segment drew notice when gold medalists Choi Ga-on and Kim Gilli said they were Cortis fans. \"We appreciated that the athletes told us they listen to our music while training hard. Everyone really seemed to enjoy it,\" the members recalled.
Cortis performed \"REDRED\" live on Noon's Hope with Kim Shin-young. Standing at vintage-style microphones, they loosened into the groove and delivered polished vocals, earning praise from listeners.
