Spoiling Me, Spoiling You - The Rich Wife's Sweet Game

Sophia is a nurse who collapses at the end of a night shift and opens her eyes in another woman's body, married to the richest man in the city. The welcome is a woman from the dead wife's circle who calls her a mistress to her face and makes a serious attempt on her life, wanting her killed alongside the man she supposedly slept with. Sophia sorts out her situation quickly. The husband, Spencer, is wealthy, good-looking and has no heir, and she is not going to keep playing the poisonous wife everyone remembers. She decides the safest future available is to make him want her, so she becomes affectionate, attentive and slightly ridiculous about it, working on a man known for being cold and for disliking women in general. He does not shake her off. He warms up, then keeps going, until the household is watching him dote on the wife he used to avoid, and Sophia has to deal with the people who preferred her as a villain.
