they're there for 3 months and he meets a different one each day so he meets girls 1-30 all 3 months but only sees our girl once since she happens to be there when there's 2 months with 30 days and one only month with 31
God, thought it might be something like that （￣へ￣）they should explain it like this in the manga, the explanation there is bit lacking xD
Which is why when his guard told him he had to treat the consorts and see them as human beings, I was like, "Dude, he's seeing thrity-one women with most three times each. He needs cliffnotes. It's already an unreasonable situation to meet someone."
I still don't get the system of meeting the consorts... Like, what kind of months they have that the king can meet all of the candidates more than one but only the 31st he meets once? （￣へ￣）
