I’m a lil lost.. is it them like “in real life” ??
It said “actors au” so it’s just them in an alternate universe as actors!
It's an actors au (alternate universe) where they are actors. Is that them in real life? Not necessarily, it's just a parallel world. Are they acting as characters from the main story? Well, the set they're using seems to be the house from the main story, so it's possible. Or maybe it's the same house but their script is different from the main story!
Honestly wanted side stories of the main story but this is pretty good too!
