Shigaraki x fem self harm reader

I have never made one of these before and I might spell something wrong I'm just really nervous I have never made a story but this story is about a young girl who is apart of the lov her name is Y/N she has had a horrible past and lots of trauma from it and she tends to blame a lot of things on her self and takes it out bye self harming and sometimes starving her self. over time Shigaraki starts to notice small things and Shigaraki starts to watch Y/N and grows worried but does not want to let Y/N know that he cares or even that he likes her what will Tomura Shigaraki do now......
