system notice: too much time in war zones and not enough time socializing has granted you the hidden ability "Dense MC Syndrome". all even slightly romantic interactions will be unnoticed unless the girl is explicitly blunt about her feelings...and maybe not noticed even then...
@InsaneInsomniac nah fam, he doesnt have Dense MC Syndrome, but he has Extreme Edgelord which nullifies any non extreme romantic development
But for real tho, these type of manhwa only have romance near the end. And by that time the female (strong or not) is usually nothing more than damsel in distress
