Sis (Soft Is Strong), released in 2024, was the debut EP of Katseye, an international girl group that emerged from the survival programme The Debut: Dream Academy, a collaboration between HYBE and Geffen Records. The group is made up of members from diverse backgrounds and aims at a global pop audience. The EP contains tracks such as "Touch", "My Way" and "Tonight I Might" and combines contemporary pop with R&B and dance influences. With this first release Katseye set the tone for a group that brings together Western pop and the training methods of the K-pop industry.
