(No golden finger, no pocket dimension, no overpowered moments. Everyday family life, and not exactly a strong female lead either. After the heroine avenges her mother, she settles into a peaceful, cheerful life.)
Nini is still a child. Little by little, she discovers that her mother did not die from accidentally eating something poisonous, but was framed by someone. As she grows up, she follows the clues and avenges her mother.
