In SMTown Paris, Krystal did not hold Taemin’s hand at the ending bow. Likewise, at SMTown Taiwan, she did not hold Leeteuk’s (?) hand either. You can see that on the left side of the gif, there is a gap between Krystal (wearing her usual skirt) and Leeteuk next to her. It seems as if Krystal does not like holding guys’ hands, even though she is close with both of them. However, at SMTown LA, she was the one who initiated the hand-holding, which makes Kaistal all the more special, and all the more fishy.
