On March 27 KST, SHINee's Key greeted viewers in a new YouTube spin-off series by the makers of Yoo Jae Suk's 'Just An Excuse', titled 'This Month's Gyewon'. 

On this episode, Key visited the dorm of a 5th generation boy group to inspect the rookie idols' closet items. After entering the dorm, Key commented, "It's been a while since I smelled an idol dormitory. It's somewhere in the middle between good smells and bad smells. You can smell all kinds of smells all mixed up. It makes me nostalgic." 

While inspecting the boy group's closet items, Key came across several graphic tees with the logos of legendary rock bands. He explained, "These are the kinds of shirts that you buy because you found it pretty, but in the end you only wear it for practices." 

Hearing this, the producers asked Key, "Back in the day, idol choreography practice videos were way more real. The idols were drenched in sweat. But now, the videos are so clean." 

To this, Key remarked, "Do you know why that is? Back in those days, we never posted any of those choreography videos ourselves. They were all leaked without permission. They were never meant to be revealed to the public. If we wanted to show ourselves like that, Taemin would not be wearing his ridiculous barcode shirt and I would not have tied my bangs up on top of my head. We were rookies!"

Key continued, "But because those leaked videos went viral, by the next generation, choreography practice videos had become their own contents."
