Favorite Day of the Week (гет)

In a month, the annual Heroes Ball was taking place, commemorating the end of the War. After much internal debate, Hermione decided she was going to ask Severus to attend it with her. She knew it was a risk. What if she’d misread his interest in her completely? Would they be able to continue working as colleagues if he rejected her? But she also knew that if she continued on in this quiet, tortuously slow dance--content only to share a sandwich and tea with him three days a week and the occasional passing touch-- she would surely lose her mind.
