Originally, Su Hongying was thinking of sending the two children to her mother's place, leaving the family affairs to her brother-in-law. She planned to stay with her husband at her sister-in-law's place for a month or so, and only discuss things after Lian Yue had recovered after childbirth.
Otherwise, with a new mom and a non-biological dad, she wouldn't feel at ease if she wasn't around to help out.
No way around it, since the in-laws passed away early, there are hardly any older family members on the Lian family side. Underneath, as the sister-in-law, Lian Hai's wife shouldn't always be hanging around in front of her brother-in-law, not to mention the small injured Lian Jie at home, the little Lian Jia, and a whole load of household chores. Lian Yue herself is pregnant; it's impressive enough if someone cares for her, there's no way she could come over to help Shuzhen with postpartum recovery.
