I don't remember all of it. Because my jp is not quite good. and I think it was last year I read it.
What I remembered based on what 'I understand' (so if I'm wrong hopefully someone can help mend it)
the old charlotte DID love the ML. but due to the contract she was bind to the royal she can't. I don't know the specific. and she was the one who sealed her own memories.
I think because the king and that prince is trash, type who abused authority. The reason she can't heal 'other people' was due to that contract with royal that bind her not her will. That's why she act like a villainess.
she is like a shibainu until the end hahahaha...
The ML ends up loving her.
but I don't quite understand at the end after ML rescue Charlotte from the prince (the prince is a bleh guy) since I don't understand some words in jp. I mean there is still that contract with the trash king, and I think charlotte doesn't remember her whole memories till the end. I don't understand if they solved it or not.
what I know is charlotte will get ML anyway.
The trash prince kidnap charlotte using a friend from a circle. likely the friend was threatened by the prince, I don't know what. but then the friend told the teacher.
ML have to fight the trash prince to rescue charlotte, he even used many items because his magic was not full yet.
I think Charlotte end up giving some of her magic to ML that he won.
that's all I remember. (that's why I am sad I can't read the raw anymore)
your welcome.
I think she remember but not all of it. and I think it has something to do with the rules in the contract with the royal.
but then again I DON'T REMEMBER IT ALL. it's bits of memory from me reading it last year with my half Japanese understanding, so I do believe there will be some mistakes in my memories.
The word that the ML is enemy in her diary, is a 'word of warning' to her so she won't fall in love to him due to the contract with the king.
she was that unable to do anything she wanted due to that contract. and the only way was erasing her memory. The FL we saw now is basically her if she isn't bind with the contract with the royal.

I just wish the other website wasn't taken down.
i've read this raw until the end. but now I can't reread it anymore and it's a year ago *cries*
