On the May 3 installment of Yoo Jae Suk's YouTube talk show 'Pinggyego', Girls' Generation's Yuri and SHINee's Key chatted with host Yoo Jae Suk and fellow guest Kim Dong Hyun about their busy and hectic K-Pop idol lives in their teens and twenties. 

While naming instances when the two idols felt hurt because of their young age, Key explained, "There are times when the staff suddenly changes the formations even after we'd finished practicing everything the way it was. For example, they'll suddenly change someone's parts. It was always so stressful. But I could never show that in front of the members."

Nodding vigorously, Yuri added on, "There are also formations where certain members are hidden from view. It's called 'storage formation'. It drove me crazy." 

Key then proceeded to demonstrate the 'storage formation' for Yoo Jae Suk and Kim Dong Hyun using macarons. He said, "For example, you can have 4 people standing in formation so that all 4 of them are shown. But if it's a 'storage formation, there are 3 people being shown, while 1 person is hidden behind the center position."

Yuri further chimed in with, "When you're the one standing in the back, you have to peek your head out so your face can be seen," while Key reflected, "These days, it's actually nice to have it, because then you can rest on stage."

Yoo Jae Suk empathized with the two idols by remarking, "Even though it seems trivial now, when you're young, you can get hurt easily by something like that."
