SISTAR showed their friendship was lasting even after disbanding.
Hyorin posted a photo of all four members hanging out together with bright smiles. Soyu is even planting a smooch on Hyorin's cheek int he second photo. It looks like the four friends got together to hang out with some others as well, and wanted to update fans on how all of them were doing.
We'll miss SISTAR, and the best of luck to all four girls.
