Super Junior's Heechul and f(x)'s Sulli put on their poker faces in a chic selca!

Heechul shared on his Instagram, "Sulli, who I love and adore most in this world, is Jinri. Choi Jinri~. We were going to take a photo of us holding hands at Gimpo Airport, but our schedules didn't match up so we couldn't take it. So we decided to watch out for each other at Tokyo Dome. Sulli is one of the two women I know with perfect complexion. Who do you think the other person is?"

Heechul and Sulli looked like the perfect yin-and-yang couple with their black and white tops. They also pursed their lips with attitude to show fans a little charisma.

Fans commented, "Sulli is so beautiful", "Beautiful Heechul and your little sister", and "Is it Taeyeon?"
