While Sheena is preoccupied and concentrated on her desktop computer, she can't really help but be concerned about Casey's condition.

At her home, while Sheena is busy and focused on her computer she can't help but worry about Casey's condition. She hadn't seen it for a long time and wherever she looked for it, she went to almost every place that her friend always went to. And even though she was busy with her work that didn't stop her from forgetting Casey.
