base on what i've understand in the novel, he rarely sleep with the empress and other concubines. as an emperor, he regard sharing a bed with them as one of his duties, too. however, when his love for yeonbin grew, he does not visit other palace (exclude where yeonbin asked the emperor to do so coz yeonbin feel like it's not right that he's the only one being visited often... it was sad ) but yep! the emperor has a health harem between concubines and empress but the harem is not romantic in context (emperor only loved yeonbin hehe)

Genuine Question. It doesn't really matter if you answer with spoilers cuz I'm okay with. SO,
Since the emperor has an empress and many concubines. Does that mean like— he'll have sex with one of them if they somehow get his attention or he favors them or smthn?
