Based on Astronomy by Conan Gray. Kind of.

You and Spencer were best friends in childhood, he had liked you since 5th grade, but you guys started drifting apart during college, as Spencer graduated early due to his high IQ and wish to work in the FBI.

You were proud of him, but you missed him. He would he lying if he said he didn't still think about you. He figured you moved away or forgot about him.

It was a weekend, and one of the BAU's rare breaks, so Spencer decided to go to a local coffee shop. Only to see you sitting at one of the tables reading a book and drinking a coffee. He was stunned for a bit but after he got his sugary coffee he approached you and sat across from you.

"Hey, long time no see.." He spoke up, giving his iconic awkward smile.
