SISTAR just dropped a music video teaser for their final comeback on Wednesday, May 31. The girl group will be disbanding after 7 years of music making.

As reported by Soompi, the music video teaser was for their track "Lonely". The song was reportedly written by Black Eyed Pilseung.

It was revealed last week that SISTAR flew to Macau to film the music video. The filming was started on May 18 and finished on May 20, with Dasom flying to Korea earlier for the filming of SBS' "Sister is Alive."

Similarly, a special clip titled "Thank you, Goodbye" was released on Tuesday, May 23 on their official Twitter account. The special video clip contained an acrostic poem that corresponded with "SISTAR."

Along with the special clip, SISTAR members each wrote a hand-written goodbye letter to their fans. To generalize, the letters contained their hopes for their fans to continue supporting them in their future plans.

On Wednesday, May 24, SISTAR released teaser images for "Lonely." However, the picture does not really give off a "lonely" vibe as the girls can be seen smiling beautifully at the camera.

The two pictures of SISTAR saw the members wearing beautiful white dresses on a park while smiling stunningly at the camera. This made the fans of the girl group sadder as this may be the last time they see SISTAR members together on a picture.

As previously reported by KpopStarz, SISTAR debuted 7 years ago in 2010 with their hit track "Push Push." The girl group is widely known for their hits "So Cool", "Loving U," "Give it To Me" and the 2016 summer hits "Touch My Body" and "I Like That."

SISTAR's Hyorin and Soyou will each be going solo. On the other hand, members Dasom and Bora will be pursuing an acting career.

Meanwhile, watch SISTAR's teaser clip for "Lonely" down below. Expect to hear the full track on Wednesday, May 31 at 6 p.m. KST.
