Reincarnated as a princess to another world

She woke up in an unfamiliar place. all she knew was that she was dead, had she survived an accident? impossible, she is not a superhero to escape death. she got up and slowly approached the bedroom door and opened it, there she saw a strange world. A free world different from the world he grew up in, cool air, quiet places, and wastelands where birds roam freely. Later some soldiers came. some were still in line, and a man approached her and said that she was being picked up.she just obeyed and didn't refuse anymore. there she was brought to the palace. while riding in the carriage he remembered his previous life.she is mary jane, 31 years old and a gangster. all his life she did nothing but kill people until his own boss killed her. he knows that his boss is killing him because of the suicidal mission that was done to him.
