Im just assuming, but they clearly had tension in chapter 35 when she says she’s not interested in men who are still wet behind bars and then the prince says “is that why you always choose men who are old and dry” referring to his father and her other men she toyed with. And in the recent chapter (38) there’s a short snippet of her red hair and he says something along the line of “once a man’s pure heart is trampled on, he becomes skeptical of women” so really, that line already says a lot especially with her hair in the background. But then again, it’s all just assumptions from me lol

Spoilers!!! These are spoilers from the spoiler forum
So the red haired sleeping with the king was arranged by the prince’s mom. So what happened was, the red haired was being targeted by the king, and bc she frequently kept bumping into the prince, and him openly admitting to seducing, both began dating. The queen found out about their relationship, and began harassing her, making her do tasks alone but red haired never wavered and did everything. The queen insisted on making the prince entertain a foreign princess, so he had no choice but to try and convince red haired to go away for a bit as he did not want her to get hurt, but she didn’t like that so they fought. Prince then found out red haired became his father’s mistress. After some digging, ML and prince found out it was his mother who sent red haired to sleep with the king. Red haired only accepted bc she was mad at the prince at that time so she did it… anyways, she tried to humiliate FL but got humiliated instead, so Fl gave her a choice, to continue being humiliated or to be released as a mistress and to be free. Red haired chose the second choice and left. Prince left his position as prince, and his mother at some point actually begged the red haired to come back but she said no. The prince and red haired don’t end up together. The prince stays single, and his reasoning was bc it’s unfair to him to live a happy life while red haired doesn’t. So, even at the end he still yearns for her.
I hope the prince falls for Adriana, cuz he clearly likes his father’s mistress. I kind of want to see what kind of dynamic the prince and Adriana will have. A girl desperate to live happily, and a guy in an unrequited/questionable love for his father’s mistress.
