After Nobara came back from one of her missions, she was convinced she should be dead, but with her strong immune system and Shoko using RCT on her, she managed to walk it off somewhat, but she was sick, so she'd be out for a week, and instead of crashing at her own place, she decided to crash at yours. Why? because you're her best friend, but she could've at least asked first.

"No complaining, you're stuck with me for the week so you can treat me like a lady and take care of me like a good little pet!"

Yikes, you have to deal with this for a week?!
