I know that he did it for his previous promise and to prove to others that he didn't kill anyone.
"Why, they want to kill you again and again? You obviously didn't do anything wrong?"
My heart is very uncomfortable, why this world, so unfair.
He smiled gently "Silly girl, what's wrong with this? My existence is an accident. Who can accept aliens? All they want to do is destroy an alien that threatens their lives."
"This is so unfair."
"There is no fairness in this world."
I shook my head and couldn't let him stay here any longer "Go away, don't stay here, you will suffer more and more."
"I'm not leaving, Alysa. I have to stay. I have to prove that I didn't kill anyone."
"But they don't believe it."
"If you believe it, will you help me find the murderer and give me an innocence?"
"I can't."
"You can, I believe you."
Looking into his eyes, I gradually gained confidence.
