Only one person in the two stories can get the final family, you in the modern world, and him in another world. You gave up everything to chase the person you loved most, while he broke the laws of the world to hunt down the maintainer, the controller of a world that cannot be killed. I don't know how long it will take for you to become the new maintainer, the controller you least wanted to be, the maintainer judge.
