He had a FULL harem of concubines I know ..
But he didnt come across as a horny guy who has a glad eye for the women .. especially a woman he knows is his mom's pawn piece AND and daughter of his 'enemy' who might be a plant (he allowed her to sidle along during court discussions), he also knows she went after XW's girl (he was happy to see XW having a love interest and might settle down in marriage)
Did I miss something in the plot?
Was it because he wanted to control her father ? But he knew she had cut off all links to the family ..
