Both are wuxias and bromances or censored BLs. Both have similar weapons - fans and a flexible sword - and fight scenes. Both MLs have similar personalities - one is an assassin since young who plays a flute, the other, in order to leave some place, took a punishment which will shorten his life, devastating the other ML when he finds out.
