[Harry Potter] I Transmigrated to Hogwarts and Developed a Split Personality

In her previous life, An Wu was completely ordinary. After dying, she became a little witch named Narcissa Aleta.

A familiar name, familiar clothes. Isn't this the Harry Potter OC she created a few years ago?

The worst part is that the soul that originally belonged to this body is still here. Two souls crammed into one body: even a Boggart would approve.

Roommate: Narcissa is always acting weird. She really likes talking to herself.

Professor: Narcissa's split personality is pretty severe. It could flare up at any time.

Doctor: How did this nice young girl end up with a split personality?

Narcissa and An Wu: No! We don't!

1. The two heroines are not in the healthiest state of mind. Female lead's perspective, no main pairing, but there is a secondary pairing.

2. There are a few fan-community elements. I'm just writing this for love of it, and I don't know how much will end up in the story.

3. Dramatic, lighthearted, and funny. Characters may be out of character. Updates are irregular.

4. My writing is terrible, so please go easy on me.
