I’m a Landlady

After transmigrating, she has no one to rely on and is forced by her stepmother to marry a man to bring him good luck. But the moment her bridal sedan chair arrives, the groom dies. What is she supposed to do now?! And once the bride enters the household, how will she deal with all the wolves and tigers lurking within? Hmph, this highly educated woman from the modern age isn't afraid of any of you. Since you've shown me no kindness or loyalty, I'll carve out a place for myself and show you what I'm made of!
