[All] The military dance was so precise and energetic that it caught my eye.

Actually, at first I didn't know much about Seventeen.
Then, I happened to see a stage video on YouTube, and it was really neat.
The military dance was so precise and energetic that it caught my eye.

Especially, I felt that it was even more cool because the expressions on stage were vivid. From then on, I started looking for other stage videos one by one.
As I watched, I became more attached to the members because their chemistry was so good. I wondered how so many people could fit together so well.
So, I naturally became a fan because of the fun of watching the stage.
