(FINALLY ME AND ALAKAN AREN'T IN THIS STORY YES. FINALLY!) To find your soul mate you both have the same thing. A mark and string, taste, likes, colors? But everyone has a mark, taste, likes, and colors? No one has a string. Well, in this case, a chain. Yugi has a chain on his choker that goes to his soul mate. And so does Yami who is Yugi's soul mate. They are close. Not like they know each other they are close to each other. Like nearby. When they get close the chain gets smaller. They go far away the chains gets bigger.
