The Prescription by Taliax is my favorite fic about this. It was one of the funniest reveals ever!!
under-appreciated adrienette moment: when adrien spent a whole weekend in the UK searching for a place that would accept a french prescription of constipation medication that he thought marinette needed
what im saying is is that adrien is canonically the type of boyfriend that would buy marinette pads & tampons and anything she needs no matter how “tmi” it is without even batting an eye and I love that for them
