Zero shot. She was, in that very chapter, reflecting on how hard of a life He Fang has had and how it was similar to her own life (since she also lost her husband). She knew she was dying, and wanted to tie up loose ends and help push her daughter forward.
Also, it’s just not that kind of story. For all the doom and gloom people have said in the comments, the story is 99% fluff. We had the backstory for He Fang, which was tragic, but not really “dark”. Nothing “evil” happened, just an awful fate. It’s the exact same with the author’s other work too. He’s not writing a series of high drama, he’s writing fluffy slice of life romance stories.
