  [MESSAGE THREAD: MOONDAE]

  Today’s TMI
  I bought really good strawberries… so good. They made me happy just to look at them. I ate a few and they were delicious.
  Anyway…
  Long story short…
  The members ate the rest of them.

  I wanted to make this video both because I’m sick of how comfortable people are claiming Moondae and Chungwoo don’t get along when that’s obviously not true, and because these two are so underratedly FUNNY together. Enjoy the video!
