for a moment, everything was okay
Peter Parker has no idea that Harley Keener is coming to New York. He meets him on a dreaded field trip to Stark Tower, finds out they're going to live together, and everything changes. His life was complicated enough without a (very attractive) southern whirlwind coming through to confuse the hell out of him.
OR
in which peter parker is an anxious bi disaster, harley keener comes in out of nowhere and changes his life, and they're both oblivious idiots.
