Just realized: the Hyouka main four are a perfect sedoretu in my mind.
morning man = fukube
morning woman = chitanda
evening man = oreki
evening woman = mayaka
morning marriage = chitanda / oreki
evening marriage = mayaka / fukube
day marriage = chitanda / mayaka
night marriage = oreki / fukube
THAT IS LITERALLY EVERYTHING I SHIP AND THE OTHER TWO POSSIBILITIES (Fukube/Chitanda and Mayaka/Oreki) I SEE AS IMPORTANT BUT PLATONIC.
What an interesting concept.
