￼Doug Billings is getting married in two days. His fiancé feels that his sister should go along with them so things don't get out of control. shit hits the fan. Olivia Billings has been friends with Phil and Stu ever since she could remember. Along with Doug, the four of them have always been inseparable. She's always sorta been the odd ball out being the only girl and all but when they meet Doug's new brother in law Alan, things start to change. Phil and her have always been close even considering her brother is in the group but after so many intense things happening to them the way they look at each other now seems to be different than before - I dont own the hangover franchise or it's characters except olivia and this will follow the general jist of the movie but definitely not word for word. Also if you couldn't tell this is a Phil wenneck fanfic so be ready for that. hope you enjoy!
