1 Introduction

Let me tell you how this world works.

There are multiple Earths in Multiverse. We are on Earth-37, where you are born and see nothing but black and white, until you find the person that you will love forever.

When you find the person that you will love forever, you will feel your heart skip a beat, and then you can see the world change right before your eyes. It will no longer be black and white. It will be colorful. And this colorful world is the main goal of the people in Earth-37.

You got it? Okay, great.
