Addy. on Instagram: "The red string theory, also known as the red thread of fate, is an East Asian belief, originating from Chinese mythology, that an invisible red cord connects two people destined to be lovers. This red thread can stretch or tangle, but it will never break, eventually bringing the destined pair together, regardless of time, place, or circumstances. It's a concept similar to the Western idea of soulmates or a destined partner."
