It may not be Thursday, but this is definitely a throwback!

Super Junior's Donghae updated his Instagram on Monday, September 21st with an old photo of himself with Sungmin, and Eunhyuk.

In the picture, the three are standing in front of a yellow wall, making cool poses at the camera. Their hairstyles were similar to '90s-early '00s K-Pop stars like G.O.D. and H.O.T during their prime. Donning loose clothes and short, thin hair, the photo definitely was a throwback for the three.

"Donghae, Sungmin, Eunhyuk, were we 15?," posted Donghae on his Instagram on Monday along with a picture.
