In the beginning of program they were discussing why the other members didn't show, and one of the MC's guessed the reason why Seohyun didn't come is because of Kyuhyun, regarding their musical together.  MC Kim Gura was teasing Kyuhyun's musical kiss with Seohyun and how aggressive he looked in the photo. 

Kyuhyun immediately got up once MC Gura started drawing on the photo to show his analysis of the kiss.

Then Tiffany defended Kyuhyun saying Seohyun's lips are very small.

I know its supposed to be a Seokyu moment but when I heard Tiffany's comment, I couldn't help but think of Seohan...Since if anyone remembered what Luhan said in Beatles Code, when he described his ideal type...

Hehehe....Just another one my observations..Don't mind me. XD
