Fanfiction Plot Idea - Tumblr Posts

HP fanfic plot idea:

____________________________________________

Snape has made the unbreakable vows to protect Harry and Draco right?..or atleast i think he did... but imagine that he did if he didn't. Basically- Everything goes to shit or idk but he decides to take them both to his secret little hut in the middle of nowhere in the woods that no one knows about and they all have to learn to live together, get over old grudges and end the war.. somehow... Harry and Draco probably fall in love idk uhhhhhhh Severus becomes some kind of father figure.. or atleast a mentor.. a lot of shit comes to light... andddd happily ever after of smth

...i need this.. like.. it just came to me and i'm about to cry if i think about how i'm never gonna find something like this

Is there any.. literally any fic that comes to mind while reading this? Or please someone write this???? i... how does one find a fic that you come up with a plot for???

I'm reading this one fic rn "The World Without Me" by Eternal Cosmos on ff.net and basically there's the battle of Hogwarts or something and the people in the infirmary are just throwing shit at the death eaters from the windows. Dumbles seeing this said something about "the 'prisoners' of the Infirmary" and that just sounds like the perfect crack fanfic title.. anyone getting inspired to write or draw something? ..anything?
