That's the thing
I don't know if it's translator messing up or it's a real thing, but sometimes the 'imperial concubine' title holds almost the same strength as an empress so it really confuses me sometimes
Like, is it an another name?
But since he doesn't have an empress, (I think) it's the same power until an empress comes, I guess

Imperial concubine usually not having the marriage ritual in full, but only a ceremony of conferring the title hence why they aren't legal wives. Concubines will also be freely gifted to anyone when they lost the favor. While for imperial consorts and the empress usually will take marriage ritual (for the empress ofc it'd be real sacrilegious and grand scale marriage)
But yes, as long as no one is the rightful wife in the harem, she'll be in charge for household affair.
But since the MC isn't a male concubine and part of the inner household officially yet rather the Emperor's person, I think the concubine actually had no right to punish him unless he really offended her.
That's not gonna end up well........I feel kinda bad for her tho..if she loses his favor her life is done....or maybe I feel bad for her because I read remarried empress..but I don't completely feel bad because she let the servant slap him and said that he will not succeed because he is 'lowly' like, girl he is from heaven...
She is stupid too like slapping someone who the emperor favors is too foolish
