Goldenise's Manga

Can some1 explain thoroughly how the in game reality shit went down. I got so losttt. Right now I think...
- female mc is real person but then brown haired guy said nope, you're a chara test run idea I got from coming to earth. So is she a chara or naw?
- male mc is game chara, so how does he come to the real world unless that's actually a virtual world, which means the virtual world is what they're all living in.
- I onky know solidly merlin and his brother are real real ppl


Aghhhh so confusing
