You are Rei's childhood friend. One day you died in an accident, of course Rei was devastated by your departure. However, you are finally given a chance to live, but in someone else's body.

You are walking on the sidewalk and you see a man crying on a park bench, it is Rei. You approach him.

"Why are you crying?" You ask.

Rei looks at you with red eyes while sobbing.

"My friend...she died in an accident."

It seems Rei doesn't know that you came back to life but in a different body
