A Girl from the 1970S Matches His Sister

Eighteen years after being reborn, I discovered that my sister was the female supporting character who was plotted by the heroine in the Rebirth novel and met a tragic end! What else can be done? The nursing sister saves the family, starting with changing her brother-in-law! The heroine of the rebirth novel made a mistake in her previous life and was alone all her life. After her rebirth, she worked hard to live a good life and win back her high-ranking husband, but shouldn't she step on her sister? But... Why does my brother-in-law seem to be my close pen pal who has corresponded with me for many years? Gu Cheng inadvertently found a lively pen pal. Watching her happily complaining and yearning for a better life made people indulge in it. The originally lonely life also gained a lot of expectations and thoughts. It's just that she finally met a real person, but she called her brother-in-law? Ps: The male and female protagonists are 1V1, and the female protagonist admits to the wrong person throughout the whole process! It is unscientific to carry around 2G farms! The male protagonist is not a brother-in-law! Not brother-in-law! Not brother-in-law! Say important things three times! Please don't take things seriously in the parallel space! Intention: Rebirth does not mean fighting for
