Watch this video starting 1:30 and following Yeri on the right side and you will notice how she walks to D&E. When it's photo time D&E wants to stay with them or Yeri literally drags Eunhyuk :D but the photographer tells them to move back. If you follow Donghae's gazes you'll notice that he keeps looking to Irene's side.
