Most people now a days die alone because they never get the chance to receive the Aichaku necklace. It’s scary, when you actually get it, because you never know who will have the other half. Regardless of gender, anyone could be using the other half.

Here in Ai no tochi, aka the land of love, is famous for its strange science advances of this necklaces. If you get the necklace, there’s someone out there wearing the same necklace and whenever you get closer to that person, it changes to a bright red color. When you’re far from that person, it changes to a pale blue. At first the necklace is white, but when both individuals put them on, the color starts changing. When you finally find that person, both necklaces will start shinning a pastel pink color and that’s when you meet your soul mate. I think it’s exaggerated when it’s mentioned as “soul mate” but there are no other words to describe it.
