Basically, it's because as Empress, she's in charge of all the banquets and setting them up in the palace. So unfortunately, she has to set this one up too. Sovieshu knew exactly what he was doing.
Even in the novel she was always worried about the people and the kingdom not just herself.
Btw the emperor's mother had her brought to raise her so that she would be a perfect empress. The previous empress told her that she would never have to see the concubine.
So I'm truth the emperor is being awful to her even if concubines are accepted.
If she won't take Kafman, I will (tho he wouldn't like me) he's utterly precious and I love him. Also, the brother is us, just all of us, ready to take the trash out.
Also big bro is speaking the pathos of the fan base, I'm pretty sure if we could we would've collectively usurped the trash fire on the throne and annihilated the trash bin he's been burning his brain cells in.
tbh i dont really care about heinley like eh he nice i guess but still meh
