Red Velvet has been promoting their songs for a long time without stopping and the girls have been very tired but still tried to put their best foot forward and try to look appealing to their fans. One day it was the day ofanother Smtown concert and they were inside their dressing room getting ready. Exo came in greeting the girls who were looking very tired. Irene who studied a book she found by her mirror opened it and a light shone. Everyone in the room including her was into the blank pages of the book. They appered on the pages like drawings.
