Du Chunmei hid her true nature well in front of Beidewang, and even scolded Beisitian in front of him, but always under the guise of doing it for her own good, using excuses like how girls would suffer if they weren't strictly disciplined, especially when they married into their husband's family.
Beidewang was deeply devoted to medicine and left most household matters to the women. He was somewhat aware of Du Chunmei's intentions but thought that the villagers were simple folks and that even if there was some beating and scolding, it wouldn't be too excessive. Things continued like this until Beisitian was twelve.
He thought that since the child was now twelve, she would have developed some feelings for Du Chunmei after living together for so many years, and he began to focus on his own matters. Then something unexpected happened, and he took the opportunity to 'leave this world,' stepping out of everyone's sight.
