My wonderful mistake

Evette Collins has always been a perfect girl, always studied hard when she was in Hogwarts. But the graduated Ravenclaw now lives in London with her boyfriend, but her relationship isn't going great, her boyfriend doesn't love her but she's head over heels for him. Ronald Weasley hosted a Hogwarts reunion party, she decides to go but she gets super drunk, and she wakes up in a room. She doesn't know where she is but brushes it off and goes home, but little does she know.
