This is why fellas, don't be too tsundere or your love story won't move forward.
Don't forget to make sure your partner free from std and use condoms still.
Granny is not a good person, I agree. She do what she had to do. When Fon Shen fall from her high courtesan position due to being pregnant, the shop almost closed due to her jilted former clients and othet shops making it hard to both Fon Shen and the shop.
Pai Rin is the backbone who bring the shop back to high end in red district again. Which is why Granny love Pai Rin to bits and she get to choose her redeeming partner.
