Sister Lu Zhongrui always stares at her brother Lu Zhongliu with a dead look in her eyes, following him like a shadow. It wasn't until a fatal encounter at sea that the brother was shocked to realize that his sister had brought the memories of countless rebirths and pulled him back from doomed death time and time again. When her mother passed away, her obsession was gone. She left a farewell message of "I won't come again" and completely disappeared from the world. In his sister's dusty diaries and novels, the brother glimpsed her pain and despair in reincarnation. She spent everything just to exchange for his peace and joy in this life. And her final choice was to silently erase herself from everyone's memory.
