In the end of the medley, the boys unfurled a banner saying: "We love you, thank you... We'll remember you." Aw, so sweet.
But don't fret, they're just saying "goodbye" to promoting their third album. After their final performance on Inkigayo today, the boys are set to prepare for their upcoming The 2nd Asia Tour Super Show II. That should be something we should look out for.
As I mentioned there were some modifications in the dance steps. Plus a wink from Siwon! ;-)
