This is a story in which the heroine and her best friend travel to the HP world together. They may have quarrels and conflicts, but they always trust each other.
The setting is SS/OC, sub-generation, this article is slow to get started, I plan to write a full-length drama, and the characters will be as close to the original as possible. But the professor's role may not be many. What I want to say is the story of two girls in the HP world, not how a time-traveled Mary Sue hooked up with her teacher.
There may be some small extras, small theaters, etc. Interspersed in the middle. If you think any part can be written as an extra, you can tell me and I will add it as appropriate.
