The email arrived, and a giggle escaped Clara's lips. "BookLover123" wanted to go to the used bookstore. Her heart felt like it had taken flight. After discussing her favourite authors for months, it was happening. This was incredible.

The bookstore was crammed with towering shelves and the scent of old paper. A tap on her shoulder made her jump. It was him, "BookLover123," and his eyes sparkled as bright as the midday sun.
