I-Interesting. We're a system ourselves (prefer alters over alternate personalities) and yeah the magical girl seems to have d-developed as one? It's interesting b-because we actually know systems who are in relationships with someone, but only a specific alter dating the person.
The guy (and magical girl) seem under the impression th-that they're the same person. When (especially with that journal scene??) they s-seem to be more like separate entities sharing a body now. Just with no memory loss (OSDD system). We don't e-expect the series to go in that direction but, we couldn't help but notice in this chapter how the Magical Girl seems to be reacting more and more in the background of his mind. Technically he wouldn't be dating his friend if Magical Girl starts dating him, a-and we really are speaking from personal experience.
Always interesting, these kinds of stories
