If you draw on yourself will it show up on your soulmates skin? Normally no But this isn't supposed to be normal, is it?

At birth were given this 'charm' its a stone cold piece of silver or gold cut into a different shape, you and only one other person will have this shape 'charm' and that other person is your soul mate. One day the 'charm' will start to warm and that day is the day the adventure of your life starts, that's the day you must drop everything and start the search for your soul mate. There's one problem with these 'charms' if your soul mate dies your charm goes black and then after 7 days you die too, that's how it works because if your soul mate dies you no longer have anything to live for, there would be no reason to your life, there would be no way you could ever be happy, so whats the point in you living anymore...
