OMG, I Got Married in Vegas!

Two families arranged an engagement between Emily Grace and William Valcor, neither of whom had met the other. Both ran from it. They ended up in the same bar, got drunk, and married each other without knowing they were the runaway bride and groom. After that they each keep up a front of being poor. Emily takes a job and does not know the CEO of the company is her husband. She wants to be treated like an ordinary employee, so she hides who she is from her coworkers. Someone else at the company passes herself off as Emily, and Emily gets pushed around over it. Her husband turns up to defend her each time, which is what makes her start wondering about William.
