If it is of any consolation, she gets over that in the next episode I believe. Interesting enough, that is due to a 'cultural' divide she and MC have that boils up some emotions in a way that didn't come off as completely stupid, given the age of the characters. She also gets a reasonable flashback explaining that mindset soon after.

I like the dutiful 'degozaru' samurai trope, and she fits it to a tee.
