Um so i have an idea if eliot just adapt lin che as his you know relative, the story will be save from the messy life they have but I suppose it is the reason why the author didn't do it so the plot will go by the feeling of historical mangas where some illegal things happens and they have to be on the run until the manga ends?..
WAIT WHAT its the END?? YOOO just when i finally see his brother nahh you've gotta be kidding me
