The Little Phoenix Is ​​Pretty Cool

I traveled through time with the system, and I thought I was the only one who had traveled through time and knew the plot of the entire book. I was reborn with the system. I knew my ending but I just wanted to live. I have lived again, this is the second time, and this time I will hold my sister's hand tightly to prevent you from leaving this world again. Hostess: I traveled through time. Did I travel from modern times to an imaginary world? I was reborn, but I have two people in one body! Who goes and who stays? But I've been in limbo for too long and I don't want to have my period again, but I can't bear to hurt her and I don't want to do this.
