What Have I Done to Us? (Phanfiction)

"I guess times change. People forget the promises they make. They move on with their lives, and start families, and wander down new career paths. I was never one of those people. I was never up for change. But Phil was." Dan Howell, a 26 year old protagonist and sometimes video blogger, lost his best friend Phil Lester, a 30 year old child at heart, to the ways of family and love. Phil adores spending time with 28 year old Milly Langdon and so decides on keeping it that way. Dan doesn't enjoy Milly's company so Phil decides it's best if he just moves on. Every day after that, Dan regrets ever opening his mouth. Will Phil ever realise what he truly left behind? (This is set in the future, that's why their ages aren't their real ages oh)
