@expensivegirl If, as Tei observed, harem did filled with aim for a political unification, with people from many different places, not only Shukara's type and taste—which is suspiciously look a lot like Tei—that would be a fair point. Here, it's kinda look less about being forced into something and more about turning the situation to ur own advantage. Otherwise, BWAT would not specifically shows Shakura acquiring a male concubine and spending time with him, and his harem is carefully arranged rather than randomly selected.
And his reaction when Tei learns about his concubines is less of a reassuring "don't worry, they're not important to me," and more like "they're not important to YOU,"
Of course, the aim here is still not to make Tei feel uncomfortable, but he still don't give him a specific explanation and it's as if he is just telling him what he should do, and as I said, this isn't about caring for Tei, but rather about idolizing his existence and portraying him not as a person with feelings, but as someone whose only task is to stand by him without worrying, without interfering in things, and to focus on being his beloved.
