[All] Seungkwan also appeared in G-Dragon's behind-the-scenes video haha

Behind the scenes video of GD Mamamoo stage

Seungkwan came out ㅋㅋㅋ

If you look closely at the video, you can see Seungkwan greeting

If you make a heart with your hands, lol

It's so funny

The magic of everyone becoming a fangirl in front of G-Dragon

These seniors and juniors look so good!!!!!
