Ahahaha you're welcome I was bored anyway (●'◡'●)ﾉ
I dont really remember most of the story but there was an event that follows the FL, where she and the rival(?)/concubine(?)/homewrecker(?) had to prepare a meal for the neighboring emissaries and they don't eat pork but the rival(etc?) almost ruins it by serving dishes with pork in them. But the FL had prepared an alternative banquet area and menu to surve them. And the rival(etc?) ends up smacking her because she ruined what she had prepared?(I think) - I don't remember what any of them look like and I don't remember what the series was about other than this event. I'll be sure to respond to all the comments so please let me know if you find something along these lines and in what chapter! Please and thank you!!
