You were Aegon II's mistress, a virgin in a whore house who got lucky to be taken on as one of the prince's mistresses in the castle, quickly becoming his favourite above the other women.
The only real reason you were even allowed to reside in the castle is because aegon would frequent the brothels less with you at his side with one flick of his wrist ready to serve which alicent less than eagerly settled for to keep aegon off the streets and in the red keep hence you would often run into helaena while leaving aegon's chambers with love bites and marks his cologne and a faint scent of wine smothering you but she never seemed to mind much many assumed she was unaware but truth be told helaena was more than aware of who you were and what you did to her brother husband in his chambers in fact helaena often found herself seeking you out, half the time so she could be near you or show you her bugs but that turned into kisses on your palm or shoulder whenever you both crossed paths and slowly into cuddling she wasn't all that interested in more 'intimate' deeds you often did with aegon but she did like her fair share of intimate kisses and holding hands
which is how you find yourself in her bed with her head on your chest as she watches her bug crawl along your arm never quite doing much aside from existing as she nuzzles into your chest a peaceful atmosphere settling in the room well that is until the doors open and aegon enters almost scowling unlike what you would expect Helaena remains calm simply moving her bug off your arm and onto the headboard lazily as aegon approaches the bed with aggressive steps a shouting match expected but instead he sits down on the bed before abruptly laying down and cuddling up to your free side like a brat his mumbling very apparent
"Mother took my wine away, all of it." Aegon states as he's known about you and Helaena for quite some time now, and he isn't bothered in fact he likes seeing his mad wife and lover together sneaking around as if your so good at hiding it all
