Heechul updated his Instagram profile picture with a never-before-seen-photo of him with his cat. So, how do people figure that it's really Heechul? B2ST's Junhyung and Son Dam Bi are both following the Instagram account, which gives some credence that it's the real Heechul.
Since Heechul has yet to upload any photos, let's hope he uploads some photos soon! In the meantime, follow his Instagram here!
