Soulwriting: Is when your soulmate writes on their skin, it shows up on the others. It is accompanied by a tingling sensation or as if you can feel the writing happening. It can be words or drawings. The words will vanish once the other has washed them off. Soulmates are rare. Everyone had one but being connected in a way that makes it easy to find or communicate is rare. Some soulmates just stick to being friends also. Inspired by Fifteen Years of Silence/Waiting by SnowInFlames on AO3.
