Key's new song "Tic Tac Toe" dance challenge is a hot topic!
Starting with Zico, then fellow group member Minho, and Zero Base One's Seok Matthew.

So many others, including Boy Next Door's Seongho & Unhak, also participated in the dance challenge~

Out of all of these, I liked dancing with Minho the best lol
