[MV] Cosmic Girl - (feat. San E) - Don't You Worry 'bout Me

Formerly Jooyi of RaNia.
To clear of up name confusion, 'koseumik kkeol' is the literal Hangul reading here.
Whereas, the girl group Cosmic Girls is an English translation of their Korean name, which is actually 'Wu Ju So Nyeo' and why they're also called WJSN.
