ILLIT is a South Korean girl group known for bright pop music, and this short clip circulates online under the title 'It's me.' The 17-second excerpt is shared mainly as a music sound for short-form edits, fan videos, and social posts, where its clear vocal hook makes it easy to recognise even without a longer song context. Its popularity comes from that simplicity: listeners can identify the group and the phrase immediately, while creators can reuse it as a quick introduction or transition. It remains in use because it fits the fast pace of short videos.
