I Couldn't Care Less About the Original, I'm Just Trying to Survive

In my past life, I was Soonjung Lee, but I died from overwork. When I awoke in the novel I’m Choosing the Sub Male Lead in This Life!, I swore that I wouldn't suffer again--I'd get rich and live as I pleased! But the side character I transmigrated into, Penelope, is nothing more than the widowed baroness of a poor territory. I need to do better--I must become wealthy! But, unfortunately, to reach my goal I'll need the lord of the magic tower's help, and he’s not exactly the nicest guy...
