Shen Lu opens her eyes to find she has transmigrated into a wasteland world, becoming the fake young lady who was kicked out of her home. With her is her equally miserable fiancé, the future major villain. Fortunately, her golden finger activates, and in this wasteland world where the average person can't even get a single hot meal, she embarks on the path to riches through food. Egg waffles, spicy hotpot, and crawfish. Braised pork belly, crock-pot soup, and egg fried rice. ... From a small stall to a small shop. Then from a restaurant to a holiday resort, in less than two years, Shen Lu's name became known throughout the world. Countless celebrities and dignitaries hold out Star Coins, begging for just one bite of Shen Lu's cooking. The Shen Family, who had used her up and ruthlessly abandoned her, regret their past actions, crying and shouting as they beg for her forgiveness. Shen Lu crosses her arms: "Sure. Why don't you slit your throats first to show me your sincerity?"

Before marrying Silas, Joyce had only met him three times. A marriage of convenience, a secret agreement, for a term of three years. She's fresh off a heartbreak — the man she chased for years told her they "weren't a good match." Silas has his own baggage: rumor says he's still hung up on a white moonlight who happens to look just like Joyce. So that's all she is. A substitute. ** In the second year of their marriage, on Joyce's birthday, she drank too much and, in front of everyone, tugged on his tie, pinning him underneath her: "You look... a lot like my husband." The Thorne family's second master, known for being rational and unfeeling, was flustered by her that night. He leaned in close to her ear and coaxed in a low voice, "Be good." The next day Joyce woke up to find her lips were swollen. This… Who did this! When she went to question him, she discovered Silas's lip was bitten. He stared at her and said slowly, "You crossed the line first." ** The scandal leaked. At a party, her ex-boyfriend stepped in: "She's mine. Who dares talk?" Then Silas walked in. The room went silent. "Yours? Since when?" "Joyce, tell me. Whose are you?" So much for the secret marriage. So much for being a substitute. This was supposed to be fake… wasn't it?
