May 20 eh. girl transmigrated and was previously a criminal investigator before she died she read a summary of a book but never got to read it after dying from overworking. She is now a princess who is looked down on and is investigating her fiancé as the serial killer from the summary. She's starting to fall in love with him and thinking it's not him. He's head over heels for her
To the person who doesn't understand why people don't like the fl for suspecting the ml: First off she's not suspecting him she's accusing him. In her mind she has already determined that he is the killer and is looking for evidence specifically proving that he is the killer. Not only has she made up her mind that he is the killer she made that determination based on an incomplete excerpt that she read before she transmigrated. Bold on the word excerpt. She doesn't know the whole story at all and has already determined the outcome. She doesn't have much evidence and has already determined the outcome. If she had started suspecting the ml after she had found evidence (because yes evidence does seem to point to ml) then it would be more understandable. However that is not the case.
