Single Daddy Billionaire

Most people would think that as a billionaire I don't have real problems. Money makes the world go around, right? I'm not exactly a guy weighed down with most people's concerns.
There's just one small problem. I've given up on love and family. Women have come and gone through my life, but I've never found a connection that felt like it'd last more than a few weeks. So, no wife, no kids. After all, I want someone who isn't just a gold-digger looking for her sugar daddy.
I wasn't looking for anything with my gorgeous new assistant Morgan. Hell, I'd hired her thinking she was married. Turns out she's been separated from her husband for years and about to be divorced. It also turns out that she's into me, which was more than willing to demonstrate by kissing me in a bar.
A little love being in the air's always nice, but the next thing I know I'm saddled with my sister's infant daughter. I might be a successful businessman, but I don't know anything about babies. Not a lot of them on my board of directors.
Morgan might be into me, but she's got her own issues for the past, a deep pain related to a child she lost, and I don't know if she can take being around my niece.
So, yeah, sometimes being a billionaire doesn't help. I have a duty to raise my niece, but that may cost me Morgan and a chance at true love.
