Like I said, a lot of story to go, I'd just hate for anything to have happened to her. She has no ulterior motives, isn't hopelessly in love, or overly formal about court stuff. She's good to have around.
No. She explains it all in detail in this update - if you haven't played it yet, don't click the spoiler.
She was with MC's brother first - and she was with him like twice. Beyond that he forced her to keep up the appearance that they were together to piss off MC, but she really wasn't. She was also never seriously with MC - remember he's been gone for months at a time for years - since before they met. They'd fool around when he was in town but because of her station, they could never seriously be together as a serious couple anyway. I'm so anti-NTR that I usually don't like threesomes, and even to me that's not NTR. Don't get it twisted.
