If you want the best fanfiction EVER of Severus Snape read Broken Silence by WitchImage. It is the best Snape fic I’ve ever read! It’s on A03. also I’m no longer active..
@SeverusSnapeFan233 just finished the story.. heartbroken it’s over but it was really good! Not gonna lie I thought the beginning was a bit different from how i pictured Severus to act but it got so much better from then on. I really enjoyed reading your comments along the way and thank you for recommending me the story!
