Cortis, who uploaded a ton of pre-debut photos to Instagram

Maybe because it's the 1st anniversary, they uploaded a ton of photos from overseas before their debut.

When I compared the photos you posted on Instagram with now, I could see how much you've grown in just a few years.

It's fascinating how much the atmosphere has changed in just a year.

For the 1st anniversary, I looked at old photos for the first time in a while, and it really reminded me of my early debut days.

I hope they don't lose the mindset they had back then and continue to be active for their 2nd, 3rd, and beyond.
