El hilo rojo (2016) online

The Red String of Fate, also referred to as the Red String of Marriage, and other variants, is an East Asian belief originating from Chinese legend. According to this myth, the gods tie an invisible red cord around the ankles of those that are destined to meet one another in a certain situation or help each other in a certain way. Often, in Japanese culture, it is thought to be tied around the little finger.
