Did you do the taming harem first? Probably not.
Multiple people are having issues with it and the 20 LP event.
FYI, if you want to be aggressive, go do it elsewhere and to somebody willing to entertain it.

"Having trouble with a possible Ayesha bug. I'm told to get to know her better and her love points is locked at 20 but the progress bar is at 80% and I can't make it go any higher".
First of all this is what was being asked about by the one posting the question. Second of all I'm just posting about my experience but you somehow refuse to believe me and only now come around with the information about the bug being linked to the harem.
