Su Jin's mission is to protect the poor people whose lives were ruined by the best scum and become a good person in the eyes of the world, so she became these best: 1. The best who dedicates herself to her husband and children for her brother; 2. The one who goes far away for love. Brain mother 3, the vicious real daughter who hates everyone equally 4, the giant baby who gnaws on the old man squatting at home 5, the best stepmother who swallowed her ex-husband’s inheritance all by herself 6, the evil mother-in-law who is suffering drama 7, an emotional liar who will do anything to marry into a wealthy family... ...When Su Jin became these people, the brother-helping demon became a child-loving demon, the best stepmother turned out to be hard-spoken and soft-hearted, and the love-brained mother returned home with a huge fortune to support her. It's a girl with a tsundere and a vicious tongue... Everyone: Ah, it turns out that we are too superficial and only saw her superficial appearance. In reality, she is beautiful, excellent and kind, and she is really a good person...
