Two me, one corpse, and a room full of butterfly specimens.
Little A and I climbed a mountain.
On the top of the mountain, two people pulled us up——
It's another me, and another little A.
Later, the man who lived in my house died.
The police came to question.
The plainclothes man in front of me changed into another face in a second.
In the interrogation room, my name was written on the file.
Two words in the red circle: murderer.
I reported that person.
He was taken away.
Walking out of the police station, little A stood under the street light.
He turned back and smiled.
The same smile as mine.
I looked down at my hands——
In the palm of my hand, there is a piece of butterfly wing scale powder.
Who is the murderer?
I have no idea.
Maybe you can't guess it either.
Concept: When you find out that you may have two, can you still believe that you are innocent?
