the princess was sent in marriage to the lord as part of a diplomatic act. They have monthly conjugal visits that... I think whether it's consensual or not is up to the reader to decide. But I don't want to necessarily label it dubcon or noncon as I feel like that doesn't credit the princess's agency and choices. I do think it walks a very fine line, and one descriptive quote/line from one such night could be taken as dub/noncon based on interpretation of what the prince says. Just read with caution if it's something that can affect you, and just know that the prince seems to genuinely love her while the princess is focused for most of the story on protecting her heart. But to me, it's clear she's been seeing over time that he is a good man, and she has also been slowly falling for him even if she's been trying not to care. I do believe that consent should be clearly established, but people and relationships are never so clearly defined from one moment to another, and sometimes people make do within their specific contexts according to their own inner priorities. This relationship and the descriptions of their intimate moments reflect that for me.
