I need help to find a story it be great if you can help.

I'm trying to look for a faberry story.

If I remember rightly it about Rachel who leaves suddenly and no one know why. Her and Quinn in a relationship so she was shocked to hear about it when Mr Schue announce it. It go on showing Rachel leaving her house with her dad in the house asking to think about her decision as she didn't get into NYADA, so she joining the army. It finishes with her coming back and meeting her dad at the airport but was surprise when Quinn ran and hug her and slap her telling her not to leave like that again. Please help me find this story if you can, I will be very grateful. Thank you for helping and your time.
