Chapter : Yang Kai's Missed/Potential Waifu's
Most of the names below were found on the Fandom Wiki, because I am too lazy to go through the entire series a third time. And not all names are here are for certain going to become a new member of Yang Kai's Harem... Yet
Total potential missed Harem Members : 65
Number of potential wives/concubines : 63
Number of potential wet nurses : 2
(Note: in this case, wet nurse count above are the number that actually go through the ceremony as if they are a concubine. But hold a position closer to that of a caretaker instead of a lover, but will still bear children with Yang Kai. This is unlike what the other inevitable wet nurses would be.)
