"Auntie, is your older brother also from Yundong County?"
"No, my birth family is from Wanhe County, closer to here. My big brother and sister-in-law moved in with us only a little over three years ago."
It's that couple, there's no more doubt about it.
"Why are your older brother and sister-in-law not with us anymore?"
"My older brother worked himself to death and my sister-in-law lost the will to live after he passed away. She caught a cold but didn't want to seek treatment and soon followed him in death, leaving their two poor children orphaned at a young age."
Overworked to death implies the family conditions weren't great, Yun'er must have suffered a lot. But the original host also suffered a lot in the Shen family and even lost her life in the end, so whether it's a blessing or a curse is hard to say...
