Writing a Diary at Hogwarts: The Witches Turn the Tables on Me

Eddie transmigrates into the world of Harry Potter and becomes Harry Potter. He's just thinking about making a run for it when he awakens a Diary-Fabrication System.

Who in their right mind keeps a diary?

What, there are rewards? Then he won't be in his right mind anymore.

And so, Hogwarts takes a strange turn.

Hermione: "What? I'm Eddie's one true love, but Ginny stole him from me?"

Ginny: "What? I'm going to be Eddie's wife, but he's already in love with someone else?"

Fleur: "What? I'm going to share a bed with Eddie, and he's after my sister too?"

Luna, Cho Chang, Lavender... When even Bellatrix starts giving Eddie a strange look, Voldemort glares at him. "Hey, you need to quit while you're ahead!"
