Hermione felt a slight sting of guilt at Ginny's reaction....but she couldn't spend every waking moment with the girl. Hermione just smiled, then turned to go, leaving Ginny's bedroom door open, perhaps as a symbol that she wasn't leaving for any bad reason, she just needed to go.
Once she was in the bathroom, Hermione sighed, kicking the door shut and heading over to the tub, starting to fill it with water, before strating to undress slowly. She didn't even notice that her kick hadn't quite been hard enough, that the bathroom door was still open just enough to peek through.
Once the tub was full, Hermione slowly slipped into the water, sighing in relief as the hot water rushed over her naked body, her skin covered in gosebumps as the hot water contrasted with the cool winter air from outside, coming through tiny gaps in the window. "Mmmmm...." Slowly, the girl relaxed fully into the water, closing her eyes as she tried to relax, tried to forget about Harry and Ron, if only for a short while.
