I admit I was a bit "ugh" when all the dudes in this chapter seemed to just be flustered and panicking over "woman having period!" because it's just treating the whole situation as a gag instead of having even one of them possess some basic knowledge.
I know they're all usually on the frontier for the most part, but one of them mentioned having a wife, so I was hoping this wouldn't be just "guy is clueless and ignorant about Woman Things" as is so often the case in all manner of media. (Like his asking the maid "isn't there a cure" to which she very understandably snapped at him in response.)
But I will give MC points for stepping up and doing what he can to help the FMC out and pushing through his panic and embarrassment to try and alleviate her suffering, instead of hiding away because "I don't know what any of this means". It's very in-tune with his character up to this point, but it's enough of a deviation from the oft-depicted basement-level attitude of men in these sorts of things that I'll give credit where it's due.
