Oversee the manager

You are a 20 year old lady, recently married off to a well off young noble lord, far from your home. Your husband isn't a baron, but he has a big enough manor and many acres of land to sustain a relatively good lifestyle. Your serfs do all the work, your husband manages the lands he owns, all you had to do up until now was try to produce an heir to him and spend your time in any way you wanted. But no heir was born so far, but you both are still young and have plenty of time to succeed. But life is about to change soon... Dark clouds are gathering on the horizon, you will have to face many challenges in the upcoming times... But if you are mindful and ready to do your best, you might get far! However, should you make poor decisions, your life won't be a fairy tale...
