A new K-pop group debuted this year, and I think they are really good and will go huge! The group name is CORTIS. The group debuted August 18, 2025. The K-pop group has 5 members. Martin is the group leader. James (Taiwanese, dancer), Juhoon (former youth model), Seonghyeon, and Keonho make up the group. James was born October 14, 2005, Juhoon was born January 3, 2008, Seonghyeon was born January 13, 2009, and Keonho was born February 14, 2009. James is the oldest at 20, while Keonho is the youngest at 16.
Although these members seem serious in their music videos and songs, they are actually very humorous and love to joke around with each other. They are all very close and seem like brothers. I love their friendship and how much they care for each other. They love their fans and are so grateful for all the people who are supporting them along the way. The group CORTIS is growing with fans and is excited for their growth.
The K-pop group CORTIS has over 300 songs. In the final writing, the group narrowed it down to the 5 songs “GO!”, “what you want,” “FaSHioN,” “Lullaby,” and “JoyRide.” I enjoy listening to these songs, and I think they are really creative and cool. CORTIS’s first album name is “Color Outside the Lines.” The fandom name for CORTIS is called COER. It was announced on their 100th debut day, combining “COR” (from Cortis) and “~ER” (those who stand together) to signify the core supporters who love and stand with the group.
CORTIS in my opinion is one of the coolest groups in K-pop history. I really recommend that you look into them and check them out. These are amazing and sweet people, and they love each other and the people that support them through their journey. They are going to make a difference in K-pop and grow big. I hope to see more albums and songs from them. Seonghyeon (lyricist/topliner) and Keonho (youngest, visual contributor). Martin is known for his tall appearance, his height being 6 feet 3 inches (190.5 cm). Juhoon is the shortest at 5’9″. CORTIS’s first album is “COLOR OUTSIDE THE LINES,” released in September 2025 by BIGHIT MUSIC, featuring tracks like “GO!” and “what you want.”
CORTIS is a small group and only debuted this year, but they have grown a lot in popularity. Their most popular song is “GO!”, streamed 56 million times on Spotify by mid December 2025. They have been gaining a lot of fans since they dropped their first album. I can’t wait to see how much they grow. I’ve only heard of them 2 weeks ago, but I’m already loving them, and I think you will too. My favorite song by them is definitely “FaSHioN” or “GO!”. I really recommend them.
The CORTIS members, Martin, James, Juhoon, Seonghyeon, and Keonho, are 16–20. The members are young, and I’m glad I’m not too late to the fandom. Martin is 17, James is 20, Juhoon is 17, Seonghyeon is 16, and Keonho is 16. Martin was born March 20, 2008, James was born October 14, 2005, Juhoon was born January 3, 2008, Seonghyeon was born January 13, 2009, and Keonho was born February 14, 2009.
