Finn Wolfhard - 1 : Promise

exactly what it says it is.^

I update every once in a while but I'll try not to do cliffhangers if it's going to be a very long time between updates. (This also is only if the story has multiple parts)
Let me know if I make any typos or mix up names please! Also some chapters have names spelled wrong for the entire chapter but I'm not going to go through it all so sorry!
