Why are you complaining about the cover being a guy and now the first chapter showing a girl?
1. The girl can also not be the MC and is just shown in the first chapter. There are a few storys like that.
2. If the girl is the MC then the guy on the cover is probably the soul she will steal or something like that.
3. You are mad that They took like 5 minutes of your life because you thought it's a fuc**** guy? I never really saw any sort of story where the MC is a girl and it's actually a bit nice to see a girl as an MC in such a kind of story (if she is the MC)
