the dude unfairly punished that lady-in-waiting because his clearly scheming girlfriend (whom he brought to the palace shamelessly) shed a few tears and made some ugu faces. the reason why everyone's mad is because our FL is such a stark contrast to the emperor, who doesn't even realize how unreasonable he's being to the empress. like cmon how can you still sympathize with the emperor when the comic very clearly sets him up to be reprehensible (and thus far hasn't shown his side of things)
