Learn To Make Mistakes - Phan

when Dan Howell comes into his life, Phil Leister thinks all his problems are solved, but he doesn't realise that befriending Dan Howell is neither his greatest achievement nor his biggest mistake. ((Trigger warning, rated M for... adult content. Known on fanfiction.net as Phan - hate what makes me. I am the original writer, however I do not own Dan, Phil, PJ, or many other characters in this story except for OCs))
