On July 17, Super Junior's Heechul posted a photo on his Instagram page of himself with TVXQ member Yunho in Osaka, Japan.

Both men can be seen standing side by side backstage after another successfulSMTown concert. The caption read, "Now matter how much I think about it, Yunho seriously looks like a Doberman. Whereas, I, on the other hand, resemble Kim Byeong Ok hyungnim."

Meanwhile, Super Junior is looking to make a comeback in October. Yunho was discharged from the military last month.
