Hong Kong Movie Wuxia: I Just Want to Be Friends with You

[The author wrote this on a whim just for fun, so please ignore it. Of course, you're welcome to give it a try and see how weird it is, but please don't criticize it.] It's kind of like quick transmigration, but not really.

The characters in the story can be understood as different slices of the same person: one person with different identities and personalities in different worlds.
