I think the bruises, cuts and scars are an EMOTIONAL METAPHOR. And not actual physical bruises, cuts or scars. I think it's just about a girl who felt hopeless and couldn't find anyone who could care or relate to her until "you" reached out to her and helped her. And I think she wrote a poem, or a song, or a story that she was too shy to tell anyone about but he found it and read it for which made her feel special and takes her off her edge of loneliness.
