This story mentions/contains boy×boy.
This story is based on "Friendly Competition" by @JayseHasNoGrace READ THAT FIRST!!!!!!!!!!
This is a time travel fic that uses the surprise at the end of the story as the main part in the story. This story won't be good unless you read "Friendly Competition".
I also promise that I am not sending 20 people into the past (because I hate when people do that) to meet the Order of the Phoenix. I'm sending 4.
