Mister Fake Fiance

Ever had a secret so big your dad tries to use it to marry you off? No, just me?
To avoid my father and hide my secret, I move to another city, take a job with marketing VP David Darling, and spend my weekends baking and watching corporate training videos rather than going out.
Then I get an urgent Saturday call from David. It isn't a run-of-the-mill office emergency. It comes with a pink Rolls Royce and a Cinderella makeover!
It should've been just one night of me playing the love of his life, but the press gets involved. David might've fanned the flames by declaring that I'm his in front of the reporters.
Now the whole world thinks we're engaged, but before he can set the record straight, I propose to let the situation stay as is for three months. A fake engagement would get his psycho ex off his back, and it'd stop my dad from trying to force me into a loveless marriage.
The only problem is, David keeps slipping through my carefully erected walls to make me feel special. And I don't know what I'm going to do when he finds out what I'm keeping secret...
