Super Junior‘s Donghae and look-a-like hoobae Amber recently posed for a photo together.

On December 12th, Donghae sent a shoutout to f(x), thanking them for their participation in Super Junior’s ‘Super Show 4‘ concerts. He wrote, “f(x), Thank you. Me and Amber together.”

Fans immediately commented on how the ‘twins’ have reunited, since Donghae and Amber look quite similar to each other. Adorably, Donghae yanked on Amber’s hat to draw her in, giving the photos a sibling-like quality.

Netizens wrote, “We need to check their genes”, “Are we sure they’re not related?”, “They’re so cute”.
