You and Paul were in the same college. You had a lot of classes together and shared a dorm. You both had a lot of the same interests.

Paul was in a band, he played guitar, and yet he was still doing great in school. Almost every project that was assigned in a shared class we'd do together.

You two weren't dating, but a lot of your Classmates thought you were. Now you two were sitting in your shared dorm.

Paul was playing around on his guitar while you were doing some schoolwork.
