Exactly what I was thinking.
The syphilis lady probably lost her value as a high courtesan, since she was deemed pregnant. And then she had to sell herself off since she was lower tiered, causing her to contract the disease. Also that guy is a scumbag— and I hope karma hits him.
To add, the nightmare memory that mao mao has was most likely because her mother (syphillis lady) hated her for ruining her livelihood. Mao mao also includes how she used to chase her out but now she’s too tired
The rocks the syphillis lady took out were the game go rocks. And earlier Rakan had said that the courtesan he Fancied always lost at shogi but won at go. It’s likely that the I’ll lady is maomaos mom
