Jung Chae Yeon said, "Before Eunchae came, Yebin, Eunjin, and I were the maknaes, but now we got a real maknae, which is nice.  She's 17."  With a shy smile, Eunchae appeared and said, "I'm DIA's maknae, Eunchae.  I'm clumsy and lacking, but please view me nicely."

When asked who gave off the best first impression, Eunchae chose Yebin, explaining, "Starting from when I first met her, Yebin treated me well.  She said she had been the last one to get into DIA [before me] and could understand me well, so she took care of me." How sweet!  That's very cool of Yebin.
