It was implied that he has a reputation of being a flirt tho not specifically to what extent. Probably he has spent nights with a lot of women tho we've only seen one thus far.
I don't think he did spend nights with lot of women if i remember correctly lady moulde was the only one who got the prince's favor was mentioned (it turned out to be just an act) it implies more about how he flirts with lots of people? Is what i think ヾ(❀╹◡╹)ﾉ~
Could be also. I actually got that impression from how adamant the FL said she don't do night services, loosely implying there's such a history in the first place. Just speculations ~
why does she keep implying he's a manwhore (lol), like is that her way of teasing him or he actually has a reputation of it? also if he does, nothing wrong with that, just asking cuz im genuinely confuse with how they talk sometimes
