[talk] SM.1 full version, the place of SM integration from 1st to 5th generation

Channel 15 nights filmed to commemorate SM's 30th anniversary!

It was so funny that I brought the video for those who haven't seen it yet haha

The first part is about self-introductions, and as expected from a variety show monster, Key speaks really well ㅋㅋㅋㅋ
