can someone tell me what is the relation of the two snakes with the chairwoman? why do they live with her?
Choi Myung-Ji is the chairwoman's sister-in-law, since she was married to the chairwoman's brother. Se-Young is Myung-Ji's daughter, making her the chairwoman's niece. I can't remember exactly why they live with the chairwoman- I think it's because the chairwoman's brother died.
A lot of people have speculated that too.
