Yuri was very professional handling her mic problem, this is just one of the many times shown that yuri is very professional and knows what to do during things like that. Let's talk about the fireworks at the end. What kind of moron would put those fireworks at such a small part of the stage, poor snsd. They were coughing so much. Aw, I hope they were ok. BUT, can we please talk about Yoonas professionalism at the end. She only coughed when they went back up to the front, like dang girl. And at the end where she said "party time", she still held her pose and smiled naturally, with no problems whatsoever. PROFESSIONAL. not to mention how seohyun made sure the girls were ok, and her and yoona made sure to say goodbye and bow.
