Leave Him, Wed a Tycoon

A widow and her small son live in the house of the widow's brother-in-law, and he and his wife look after both of them. The wife is an orphan with no family of her own. She is pregnant and close to term, and she works as a food delivery rider to put money toward the settled life she is counting on. One day she walks in on her husband and the widow together. There is nobody she can turn to, and she is stuck inside the marriage. A man with money and standing steps in. He helps her get out of the marriage and set herself up on her own. The baby will need a household registration, so the two of them sign a marriage agreement to make that possible. After the wedding she learns that he has loved her for a long time without saying so, and she starts to feel the same. Then his own brother's wife comes back from overseas. She has been through one sister-in-law already and expects the same thing again. His family, every one of them, treats her as the most valued person in the house, and the damage from the first marriage begins to heal.
