Behind-the-scenes photos from Key's Taiwan concert were posted on his Instagram. They're hip and cool.

As expected, he is a photography expert.

These are so cute and pretty pictures, I love them

It touches my heart to see you always upload photos with such care for your fans.

The kitschy expressions in the photos are also really cute.

These days, your skin is glowing and you look so cool

As a fan, I'm so proud to see that he maintains his popularity and consistently appears on variety shows despite his busy schedule.

I feel so proud when I see you faithfully doing your broadcasting activities without any controversy.

The scenes shown on Nahonsan are always nice to see.

The human side also stood out.

As a fan, I hope you become an even more successful singer, entertainer, and artist.

I hope you always stay healthy and work hard.

Fighting!
