Emperors were not exempt from criticism. Power did not make one unable to be judged—it simply inspired fear and discouraged people from openly judging and feeling the same lack of care for consequences as they would when dealing with a person of equal stature.
As emperor, Kiyoomi didn’t fear judgement. However, that didn’t mean he didn’t understand political necessity.
As opposed as he was to the culture of concubines, he was expected to take at least a couple from several well known families. He didn’t particularly do anything with them, not entirely focused on producing a male heir so early in his reign.
He was also not immune to male favorites, who stole the majority of his interest. When he was free from duty, he often drifted towards his male favorites or, rather, a particular male favorite.
