Frozen Heart: A billionaire romance

My new boss is gorgeous.
He's also cold as hell.
No one's gotten through his icy walls in years, and it makes me wonder if there's any way to reach his heart... or if he even has a heart. If he does, it's been frozen beneath the ice for a long, long time.
Someone really needs to thaw him out... and I figure I'm just the guy to do it.
