Brother War: My Sister Is a Little Transparent

Brothers War fanfic, the tone of the whole text is warm and slightly dark, the writing style of the stupid author is average, the plot is wild and unconstrained, the heroine is a soft and cute girl that I like (original), the golden finger is wide open, the content and character are Su Susu, it is probably 13to1, not 1v1, friends who cannot accept it are not allowed to enter, because the stupid author has a glass heart, please be merciful and don't troll::>_
