1, I am an exorcist.
You should keep your promise, apologize if you do something wrong, and take good care of his dream until the end. This is what a family member should look like.
The greatest luck in life is knowing you, and the greatest misfortune is not having you.
4. If one day, even you fall into darkness. I will do it.
I'm not human, and I don't know much about human feelings.
