Close to the beginning of their “90’s Love” stage, all the members knocked out their playful parts of the choreography. Winwin and Yangyang shook hands; Mark and Ten danced together; Mark and Winwin slapped hands.

After Haechan gave Ten a hand slap, Sungchan came sweeping right in for their fist bump. That wasn’t what Haechan had planned, spinning away from him.

Sporting a major smile, Sungchan couldn’t keep a straight face from Haechan’s antics. Even though he’s not too experienced on stage, Sungchan smoothly moved onto the next part of the choreography.

Haechan couldn’t keep a straight face either, smiling just as bright as Sungchan from the funny prank he’d quickly come up with.
