The heroine's parents died, and she met an old-timer male protagonist who was much older than her. She started a life as a heroine in a refreshing novel (you don't understand the sweetness of the elder brother), but she didn't know that the life behind her was full of dangers.
Neither the male or female protagonist is a good person)
Mainly emotional lines, but also some other character emotions.
Sweet at first and cruel at the end! ! !
Concept: Slightly Stockholm plot, entangled emotions of love and hate
