Hwang Eunbi and Jung Eunbi have been friends since they were kids. Sometimes you take these kind of friendships for granted. Othertimes you get reminded just how precious they are. Hwang Eunbi had taken it for granted for far too long. But Jung Eunbi has something special planned for a very special day.

Based on an episode of Idol Radio:

"For me, Eunha-Unnie is a photo album. Because not long ago, she gave me photos on a USB stick and there were our childhood photos. I felt emotional. So, she’s so special like a photo album, the existence written in my memory.” - Hwang Eunbi
