The bond between the SISTAR members is still going strong!

On April 3 KST, Soyou took to her personal Instagram to share a pair of photos of the SISTAR members meeting up backstage at her recent solo concert 'THE LIVE: NIGHT.' In the photo, the four are seen comfortably leaning against one another as they pose for the camera. Soyou captioned the set by telling her followers the visit "became a huge strength" for her.

The same photos were later uploaded by Hyolyn and Dasom to their own Instagram accounts, this time paired with supportive messages for Soyou.

"Our You's first solo concert. She looked so happy, so I did the same and was happy too," Hyolyn wrote.

"Our third unnie's first solo concert. She was so awesome. Fighting, today as well," Dasom added.

Fans reacted excited to the photos, leaving comments like, "It's really so great to be able to see you all together," "I love you, SISTAR," and "We'll always remember you."

Meanwhile, Soyou's 'THE LIVE: NIGHT' concert was held on April 2 at Sogang University's Mary Hall in Seoul.
