WARNING: MATURE CONTENT! I never should have applied for a job to the Cromwell's Corporation–because the only available position is to become his fake wife...

But to be honest. Sadly, he's also the one who could save my mother's failing health. So, when he offered me the chance to work with him; to pretend as his fake wife, I accepted it. Besides, it's only a couple of days during his family's visit. It's not like I'm in danger of falling in love with the most notorious bachelor in town. But at the end, I eat my own words–ended up falling so hard for him.
