If she really wants to run away from the prince, she should have done it while he was at war

Right!! I'm tired of FLs deciding they are going to run-away, but need one last glance at the MLs they are escaping from. Nah, that only gets you caught!! Like now.
This FL had time to not only cut her hair, dye it, and leave the area for good, all while the ML was fighting at war. She had no need to stick around for his welcome home parade. My sympathy meter = 0 (or at 0.1% since she doesn't deserve the I-found-you-rape-trope.)
Why japanese mangas usually in black and white? Why not they be like the Korean mangas?
is this your first time reading a manga? Well, to answer your question,, it's because the printing is cheaper that way
its because, usually, mostly mangas have physical copies (i think i spelt wrong but idkk) so its much more cheaper to print a bunch of b&w pages than colored ones
in the other hand, manhwas are not comercialized that much in physical copies when compared to mangas so thats why
