Naruto never touched his soul mark. He had no idea why everyone always thought they were such amazing things when his only brought to him the same negative emotions he already felt in his daily life. When Naruto touched his soul mark he was bombarded with sadness, loneliness, anger. The older he got the more intense those emotions became until they transformed in to rage, hatred, even bloodlust.

So Naruto learned not to touch the mark in the crook of his arm, only brushing past it when he had to clean himself or by accident. He picked himself out a nice jacket and tried to wear it as often as possible, even inside his own sad apartment. He lamented that his soulmate seemed to have had a life similar to his own, broken from the beginning with no one to help them heal, and he wished often that he could offer comfort even as he knew it would be next to impossible to find them.
