Does she try to get on Ginny, now that her predicament is over??

Yes, in the library

The next morning, Hermione's embarassment from the prior day had not cooled or disappeared; it had crystallized into a sharp, cold point of focus - Ginny Weasley. She had cast a spell that made moths eat her clothes piece by piece, leaving her completely naked in the sight of all of her friends, after making remarks about her "know-it-all" tendencies and her cozy friendship with Harry. But a day of nudity around Snape, Fitch, and Dumbledore had been the final straw. She would be the catalyst of Ginny's embarrassment.

Her search in the library the night before was precise. She bypassed the standard charms section and delved into the Restricted Section, using a note forged in Snape's familiar, spiky script to gain entry. She found what she was looking for in a dusty tome titled Maleficia Minuta: Minor Curses and Their Uses. The spell was Unravelitus Paralyticas - a cursing spell which allowed clothing to slowly disintegrate and unravel, leaving the victim blissfully unaware of their situation and their increasing nudity even after the last item of clothing had long left their body, lasting for a further 5 minutes of naked bliss.

Hermione, now once again dressed, pointed her wand and slowly cursed the incantation onto Ginny who was reading a book solo. The light flashed a brilliant crimson red all over Ginny who didnt feel the slightest thing as she continued reading, but her white shirt had a thread undo itself from her collar, which would unravel her shirt, and a 2nd thread which would work on her trousers.
