read the novel and from what i can tell it is a similar situation to koihime muso, in which a male is sent back in time and finds out historical people are girls
@cgr it isn't koihime musou, there is actually a novel of the same name if you search it up on NU, quality wise I say it's so so, it's not bad but it isn't exactly that good either so yeah quite average. readable for those interested on the three kingdom genre, but pretty much generic for those not into it
