Well, her sister has been using her name the whole time, so she IS Avril (and people know her sister, aka the villainess, as Avril and not as her real name Corina), it's just that people are realising that the rumors about her being a villainess are either fake, or done on purpose to drag her down.
No one knows her sister yet so they haven't come to the conclusion that she is being used as a scapegoat for her.
I'm lost, does everyone know she ain't the real avril as in someone is using her as a scapegoat or do they only know she ain't a real villainess?
