The red string of fate is the belief originating from Chinese legend that an invisible red string connects everyone who is destined to meet. According to the legend, the gods tie an invisible red string around the ankles (or pinkie fingers) of those that are destined to meet each other or help each other in a certain way.
The two people connected by the red thread will find each other, regardless of circumstances. The string may stretch or tangle, but never break.
Well, how about that?
