Your Colors on my Wrist

Soulmates were a beautiful thing to have.
At the age of 13 you can see the initials of your Soulmate on your left wrist start to form, which are also known as a soulmark. The soulmark is rather small, barely noticeable if you're not taking a closer look at it.
At the age of 16 you are able to communicate with them by writing on your body.
However you can't write any names on there, not yours or one of your friends. If you do then it would only appear as scribbled lines for your soulmate. However you can still write either nicknames or the initials of your name.

Komori is scared of Soulmates, Osamu and Suna are there to help him over come that fear.
