Red Velvet appeared on SBS radio program 'Kim Chang Ryul's Old School' on March 30 and talked about the addition of Yeri as a fifth member.

When Yeri was asked if it were hard joining the group later on, she replied, "There was no particular hardship to overcome as a member of Red Velvet," but continued, "Because I'm still a student, if I go to school, my friends react with, 'Huh? �It's Yeri,' which is awkward."

As Joy used to be the maknae before Yeri, she was also asked a question: "Your position as maknae was taken away with the addition of Yeri. �Is there an aspect that makes you sad about that?"

Joy replied, "I am not upset. �It is true that I'm not the maknae, but I also feel more responsibility because I'm no longer a minor. �As my affection for the team also grew, I can do anything for the team."

Kim Chang Ryul asked, "Then can you ruin your image if you need to ruin your image as a promise for winning first place?" �She simply said, "It's already ruined. �When we made a comeback, on the broadcasted 'Ice Cream TV,' we did this thing where everyone makes an ugly face, but I thought that everybody was too pretty to ruin their image, so I just ruined my own. �The capture from that scene was shown here and there."
