Fanfic I submitted to my English teacher

I may or may not have submitted a fanfic to my English teacher
Allow me to explain.
We had to write a story using like 15 vocabulary words to prove we understood how to use them. I didn't know who my characters should be so my friend gave me two names. Dean Winchester and Stiles(who I don't actually know jack about). And then after grading said paper stopped me after class telling me that my writing is really good. He even asked if I write a lot. To which I told him, "sorta." He asked what I write about, and me not wanting to tell my teacher that I write fanfiction, told him that I write about pre-existing characters. BUT! He then proceeded to ask, "Oh so you write, what is it- fanfiction?" My English teacher knows I both write and read fanfiction now!!! When he said, have a good rest of your day, I've never walked so fast out of a room in LIFE! Lemme tell you
