Former The Ark members Lee Suji and Euna Kim express their strong friendship on 'The Unit'

During the rank announcements, Euna Kim was announced first as she came in the 7th place. She was briefly interviewed and was asked how she felt about performing together with Lee Suji, her former member, through a new song for the first time in 2 years. Euna Kim replied, "Recently, she and I both made the top 9. When I saw that I cried a lot, it felt really good."

Afterward, Lee Suji was called up as she successfully came in the 5th place. She, too, was interviewed as Rain said, "When your name just got called out, the person who seemed to be the happiest for you was Euna Kim." Lee Suji said, "The person who helped and led me to come on 'The Unit' was Euna unnie. I thought to myself a lot that I wanted to [perform] with her even at least just once more. I'm always just thankful for her existence/presence."
