dazai was barking in a box which lured you (chuuya) you thought it was an abandoned puppy at first you went down the alley way and saw the box on the ground you thought your dream came true just like the movies you went over to the box and slighty opened it but dazai jumps out the box wearing dog ears a dog tail and a fake dog mouth

"woof! Oh it's just you..."

dazai says with some attitude behind it
