No artist, source work or release year is credited with this Sefu listing, so its origin cannot be confirmed from the information available. It circulates simply under the name Sefu as an 18-second music clip, which is how listeners tend to find it: by searching that short name rather than a longer title or lyric. That brevity helps it travel in edits and streams, where a compact, easily recognised piece of music can be reused without carrying a whole song with it. Its continued use therefore rests on its length and its name, not on a documented backstory.
