CORTIS signaled a more raw charm with their new release. It contains the free-spirited charms of the members.

CORTIS released photos of their second mini album 'GREENGREEN' on official social media at 9 p.m. on April 6. They were seen roaming the streets of Seoul, under bridges and in front of apartments.

It was set against places meaningful to the members. They took a group photo in front of 'Sinsa 2 Overpass' (Gilmaujunggyo). It is a road that CORTIS actually used to pass during their trainee days.

The fence in front of the apartment is also a place they passed every day. In the lyrics of their debut album title track 'What You Want,' the "fence" in the line "If I have to go back, I'll just climb over the fence" refers to this very place.

They are also carrying out a unique promotion. When each version of photos is released, a specific member directly leaves a review of the location on Google Maps. They share memories and stories related to the filming locations.

In fact, Seonghyun wrote in a review of 'Sinsa 2 Overpass' on this day, "During my trainee days, I always passed under this bridge, so it is a place with many memories," and "When I went back for the album shoot, it reminded me a lot of my trainee days."

CORTIS will sequentially release five versions of 'GREENGREEN' photos until April 10. On April 20 at 6 p.m., they will pre-release the title track 'REDRED' from 'GREENGREEN.'
