As noted in the title, I'm looking for a quick transmigration novel that I dropped and want to pick up again. The latest arc I read had the MC as a spoiled daughter of a mayor who was a delinquent. She decided to become a good student to attract the ML who was the cold aloof school prince. The female antagonist was the daughter of his family's chauffeur who had delusions that the ML liked her. After being rebuffed she decided to blow up the race car the FL was driving but she miraculously recovered. She died in the hospital despite from a bomb. The arc ended with the ML crying as he held her corpse. I apologize if the post is a bit long and thank you in advance.
