(No golden fingers, no space, no openness, short-sighted parents, and not a big heroine. After the heroine avenges her mother, she leads a plain and happy life.)
Nini is still a child. She will slowly discover that her mother's death was not due to accidental eating, but someone framed her. She will grow up slowly, find clues, and avenge her mother.
Take grandma to live a happy old life.
