Wen Yu died in a fire in her previous life. After her rebirth, she moved into an old apartment just to prevent the fire in advance. She recorded abnormalities by the window every night, which attracted the attention of firefighter Xie Shi in the building opposite. Xie Shi took the initiative to approach her, but said what she said in her diary: "You were also waiting for that fire, right?" It turned out that Xie Shi was a firefighter who rushed into the fire and died to save her in his previous life. He was reborn with memories, but he knew one more truth than she did - the arsonist was beside her.
