When Shen Yu was twenty years old, she accidentally discovered that her adoptive father, who raised her, held major secrets regarding her life experience. She chose to continue staying at the Shen family, acting obedient and sensible, secretly avoiding others' gazes, and spending three years quietly collecting relevant clues. At her adoptive father's sixtieth birthday banquet, Shen Yu publicly produced all the evidence, exposing her adoptive father's long-standing gentle and charitable external disguise. She did not want to vent resentment, but only hoped to push aside the layers of fog, restore the buried past, and seek out delayed facts and justice for deceased loved ones.
