The author of My Fair Beauty (Rebirth), fried rice with meatballs.
The man is almost thirty, and the woman just arrived, about 15 years old. At first, there were harems and children. I seldom went to the harem for a while before I had a woman, but I went one-on-one after I had a woman.
The woman later gave birth to a son and a daughter.
There is a difference in age, and a woman is reborn, but it doesn't help except to avoid the queen's marriage at first according to the memory of her last life. The story is good, but it's a little missing.
