Modern AU where Sandor is in his last year of school and is selling his textbooks online in order to make some extra cash. Sansa would rather spend her money elsewhere and goes looking for a bargain, finds Sandor’s listing and contacts him via text. They decide to meet at the library for an exchange and Sandor is busy writing in a corner when Sansa approaches him. She rambles on about traffic, bad drivers, her phone battery almost dying and when he looks up the words fall mute on her tongue. He is just as stunned, though his expression is uninviting by default. She shuffles over the money and he hands her the books then she makes a speedy exit, but not without taking one quick glance back at the man with the burnt face.
