Famous mythology heavily used in japanese culture, originated from a chinese legend. It’s an invisible red string tied around one little finger of a person, that connects them to those who they’re destined to meet and love, regardless of place, time or circumstance (also many times called soulmates). The string may stretch or even tangle, but it will never break. Not even death can tear it apart – it’s the representation of the most strong connection between two souls, united forever by the universe.
