Wow, Fooly is more than just a weak mage. The abs, and what muscle we cant see mean she is heavier than the average athletic woman but, more importantly, her armor and weapons must add 60lbs.
So "treating someone as a woman" means forcing yourself onto her, exploiting her weaknesses until she likes it, some light sexual harassment notwithstanding? I've seen this idea of "romantic comedy" in manga before, and sadly I am not a big fan.

What manga have you been reading, nothing of what you mentioned has ever happened. If you're talking about the latest chapter, he didn't try to take advantage of her she was hit by the "lust" spores and only acted "lustful" when he was hit with the same spores as her.
