After teasing Bora‘s seductive video bit yesterday, Starship Entertainment released the second music video teaser for SISTAR‘s comeback.

This time we have leader Hyorin set on a rainy night. Contrasting to Bora’s video which exudes a fun, party atmosphere of Sin City, this teaser shows a saddened Hyorin as she sits alone in a car with a lovelorn demeanor.

Slipping out of her yellow dress, Hyorin changes into a sparklingly metallic grey halter dress and enters the night life of Las Vegas.

“Alone” is the title track for SISTAR’s first mini-album which is set for release on April 12, 2012. 

Stay tuned to Soompi for more news on their comeback!
