"I am a person without a past and a future. Sometimes when I stand in front of the mirror, I can't tell which one is the real me. If I disappear from this world, no one will find out."
"Fortunately, I didn't kill you."
"Ten years from now, if you still remember me, come find me here."
I came to find you, and I still remember you. And you?
It's great, this time, I don't have to look at your back anymore.
You can stand back to back and fight together.
Let me repay the ten years of watching each other with this life...
