The Han dynasty favored black and red, ink and vermilion blending into one.
Guo Jia is the male lead, and that's settled.
It may be comedic, but it could suddenly turn tragic. It's wartime, after all, so please bear with it. The ending will definitely be great.
It may follow history, the TV adaptation, or take a nonsensical turn...
The characters listed as supporting cast aren't necessarily the second or third male leads. The male lead and the others may take their sweet time making their entrances?
This story has no limits, but I will never bash any character. Any character.
