Karen Akagi reincarnated in another world and was the daughter of Duke Karen Brad. She was educated as a queen, and even became the fiancée of the first prince, Yuri White, but she was hated as a villainous daughter and was executed. As she pierced her death by the king's blade, the last thing Karen saw was her fiancé Yuri's grim face looking down on her. She (she still hates me at times like this...) realizes that she is not loved by Yuri, and she despairs. (If I could do it all over again, I would be happy this time...) When she woke up again, she was in the real world. Five years have passed since then, and Karen lives as a normal member of society. From the trauma of being executed in another world, she had decided that she would never fall in love again, but one day a man suddenly appeared in front of her . Yuri Shiramiya (Yuri Shiromiya). The man suddenly snatches Karen's girlfriend's lips and says, "I am Karen's fiancée." She realizes that Karen is the fiancée of a man who is supposed to be in another world, and that she is the first prince, Luke White. She wonders why Yuri is in the real world, and why she is obsessed with Karen. I can't escape from the obsession of the prince who fell into darkness after the villainess' death... ! (MTL)
