@cijim suggested: Ed Sheran was discovered by Sheldon after watching game of thrones premier and then he listed to a romantic part of a certain song and gave him butterflies thinking about how in love he is with Amy
Sheldon was across the hall from his apartment watching Game of Thrones with Leonard and Penny. When he watched at home, Amy sat alone in the corner reading a book. Sheldon couldn’t drag Amy into it no matter how much he tried. He had more fun watching with Leonard and Penny even if they always made jokes about how he should go home.
