My Baby Plan Got Me a Prince

The marquis's household needs a son before the inheritance can be settled, and the marquis cannot father one. A girl was married in to bring the house luck, and she is the one expected to produce the heir. Melissa wakes up in that girl's body. She is twenty-eight and has never been with a man, and the household is already counting the months. She works out that she will have to get pregnant elsewhere and pass the child off as the marquis's, so she goes looking for a good-looking scholar. The man she picks is Vincent, the crown prince, who is hard to read and trusts nobody. She gets her night with him and it does not end there. He keeps turning up afterwards, and she goes on covering for what she was actually doing, so the two of them spend a long stretch circling each other while the household waits on its heir.
