Slap the chest then kiss the finger and point to the sky. I guess this hand gesture is familiar with you. Minho always does this move whenever he win something or when he succeeds in doing something. Same for Yuri and she did this move quite a lot, too. Minho and Yuri used to do this hand gesture alone but now they start doing it together ^.^

At SM Town Paris, they did it before high five with each other in the dance battle and they did this not just in Day 1 but Day 2 also ^^

At SM Town Tokyo Special Edition recently, MinYul did that hand gesture then give each other high five whenever they saw each other xD

This hand gesture is like their own sign. Is this the way they show their love to each other or just an excuse to touch each other's hand? I think it's both ^_^
