[Harry Potter] Amnesia

Female lead: Even if I've lost my memories, it doesn't matter. Since I've transmigrated, this world is definitely my home turf!

The Chosen One: Even if I've lost my memories, it doesn't matter. Since I've been reborn, this world is definitely my home turf!

The Chosen One's nemesis: I haven't lost my memories, but since I'm here, this world is definitely my home turf!

(Not really)

P.S.

1. The female lead is sometimes cold, sometimes cute and charming, sometimes a murderer, and sometimes a law-abiding citizen.

2. Some characters are portrayed as villains from a particular character's point of view. (When you're seeing things from Voldemort's perspective, of course Dumbledore seems like a bastard. The characters don't have an omniscient point of view, after all.)

3. I have the twisted fan mindset of loving someone by bashing them. If this bothers you, make a speedy escape through the top-right corner.
