Rider
Rider followed them out of the door, still feeling down about ruining Sakura's good mood with her picture. She watched as Shirou took Sakura into a hug, her mood lifting somewhat as she saw Sakura smile genuinely at him as he asked her why they were waiting. Then, she heard Sakura's reply.
Just get rid of it, we can figure out what to change it to later, please, Sakura said, begging her. That picture is unfair.
Rider frowned once more. She wondered what was "unfair" about it, but she didn't want to ruin Sakura's mood again. Instead, she thought for a moment, before coming up with an idea.
Hmm, Sakura, could you and Shirou turn this way, and smile? she asked, putting her phone into camera mode.
It wasn't perfect, but any photo of Sakura with her beloved would be better than a dreary blank background, and she could always find something better later.
