Changsub posted a picture from Incheon Concert on Instagram.

Changsub, who is busy with his national tour, uploaded a review photo from the Incheon concert.

The audience seats are full and it's a great view.

The atmosphere seemed warm and nice.

As expected, the ticket power is still great.

I like how the band members look so harmonious together in the group cut.

I guess you could say it feels like there's a lot of leadership.

Not just anyone can do a national tour.

Every year, when I see Changsub successfully completing his national tour, I also realize a lot of things and think that I should live diligently.

I think it's a promise

As a fan, I hope you continue to be active in various fields.

It's great now, but I hope you live an even better life.
