I recommend "My Little Cute Wife" and "Time Travel, Good Farming". The female lead of "The Cute Daughter-in-law" was a modern elite woman who had traveled to ancient times. She was very good at cooking and had a gourmet system. She became the daughter-in-law of a family. The male protagonist was gentle like jade and was a good husband who doted on the female protagonist. The female lead of "Time Travel Good Farming" was also very good at cooking. She also brought a cheating weapon, the Space Embryo, to an era that did not exist in history, turning a small farmer's family into a noble family. The male protagonist and female protagonist supported each other until they were old. They were a warm and loving couple. I hope you like my recommendation. Muah ~
