For their photoshoot, ELRIS decided to go with two different concepts - the first concept showed their romantic look while the second featured them in a much more casual look. 

Afterward, a short interview took place with ELRIS where they explained the meaning of their group name, stars/artists they've looked up to, and more. They first explained what ELRIS exactly means, "It stands for Excellent, Lovely, Rainbow, Innocent, and Sister. Because every member is still very young, we would like to continue showing our innocent, pure sides."

ELRIS' Hyeseong was also asked which star she is a fan of. To this, she replied, "I'm a fan of IU and Suzy sunbaenims. During my trainee days, I filmed a CF with IU sunbaenim. I would like to properly meet her next time and give her our CD."

Lastly, the girl group picked Red Velvet as their role models. "We were envious of Red Velvet sunbaenims' Pyeongyang concert. We aim to perform on a big stage such as [the Pyongyang concert]. We would like to be a group that's able to show strong synergy when together but also individual charms, just like Red Velvet sunbaenims," ELRIS explained.
