BEAST definitely has their quirks and thank goodness for us B2uties that not being able to stay silent about their comeback is one of them.
Doojoon, a bit late on the teaser bandwagon, posted the same photo as Yoseob and Junhyung did and wrote "Butterfly Teaser Let's Go". Junhyung then released a teaser of what we may assume to be a screenshot of a music video? Dongwoon also soon posted the same image. And Yoseob sang us a line from the song (난 아름답게 날아가 -> I fly beautifully) and wrote "Good night♡ Sleep after watching this butterfly teaser 1876494600 times♡" You can click here to go watch the video!
