Don't Let Me Go (Larry Stylinson One-Shot)

I couldn't believe it. Why? Why was this happening to me? To us! Things were going so well!

Based on the song "Don't Let Me Go". The one what Harry made a cover of and apparently helped writing. Idk really well but this is based on what I understood of the song. if you have a different interpretation of the song I'd like to hear about it :D
