[Smart female protagonist who pretends to be good x possessive and love-minded male protagonist] Ji Yan is bound to the self-rescue system. Good news: It's a heroine with a heart-throb configuration. Bad news: It's the original heroine. When the eldest sister who came through the book counterattacks, she will be thrown off the cliff and her body will be destroyed. The system gave the first task: to capture Ji Shenghan, the adopted brother of the Flower of the High Mountains. She risked her life, sat on his lap and called her brother, which made the old lady faint. The task failed and the system was disconnected. She began to have nosebleeds and was at risk of dying. The system only dropped one sentence at the end: Find the golden silkworm Gu, or die in a year. The only thing he has is a villain who kills without blinking an eye. She fled to Miao territory overnight and found Lou Shu, who had lost his memory, by the river beach. Take advantage of his illness and kill him. The empathy binding was successful. She lied to him that they were husband and wife, and he loved her deeply before he lost his memory, and he became like this in order to save her. Lou Shu believed it. … Lou Shu lost his memory due to an accident. When he woke up again, there was a silly girl beside him, calling herself his sister. He couldn't remember what happened during his amnesia, so he could only believe it. What should I do if I fall in love with my nominal sister? What else can be done? Of course it's his. … The day Ji Wei finally got the golden silkworm Gu, she ran away without looking back. Three months later, on the dusty official road, she met Lou Shu again. She was about to pretend that she didn't know him, but he grabbed her wrist. The tenderness in his eyes was completely shattered, leaving only darkness and madness. He held her tightly, his voice was hoarse and paranoid: "Sister, didn't you say you want to be with your brother forever?"
