Rhine

You died due to the overload of your work since you did not eat well and barely slept, one day when you were going home you fainted and fell onto the train tracks, you died in that accident. When you got up you thought it was just a simple faint, when you saw the sun's rays passing through the curtains you got up quickly thinking that you would be late for work, you pulled the sheets and saw your reflection in a mirror, you did not recognize yourself immediately since because of work you did not usually see your appearance, when you looked at yourself for a few more seconds you were really surprised and you saw your surroundings, you realized that you were not in your reality and you looked out the window, when you saw the protagonist of the novel that you read in your youth you immediately realized that You had been reincarnated in her, when you approached the mirror again seeing that you were reborn as the villain, who had an obsession with his son that he mistreated for being a bastard son, who years later killed you in revenge.

(reincarnation, bl, novel)
