An Hao leaped, thinking she had died, but to her surprise, when she opened her eyes, she found herself back in the year 1985. To live a second life, did she have to endure the abuse of her stepmother and stepsister again, the dislike of her mother-in-law and disdain from her sister-in-law, and the betrayal of her best friend who bravely became the other woman just to slap her in the face and climb the social ladder? Was she supposed to end her miserable life in poverty again? An Hao's answer was, “Eat! Shit! No!” She was determined to make something of herself, to get rich by capitalizing on her knowledge and aim for a well-off life. This time around, she was going to be the protective big sister who reformed her worthless little brother who had died a wretched death, and the virtuous wife to make up for her past neglect of her husband! She wouldn't let this life go to waste in despair! A malicious best friend? Coveting her man? Not a chance! Go hang out wherever it's cool! Cough cough, how did she not realize in her past life that this “Stoic King of Hell” was so indecent. Decent? You've had your fill of decency during the day.
