Billionaire Fake Husband

Imagine if the devil wore a suit, always with a stern expression, and had high expectations for everyone around him - that'd be my boss. Today, unfortunately, isn't my best day; being summoned to his office usually spells trouble. But things took a surprising turn when he asked me, in a somber mood, to consider marriage. The catch is, saying "no" doesn't seem to be an option for him. Now, does this sudden change in dynamics mean I should affectionately refer to my demanding boss as my "pumpkin boo"? It's a perplexing question, to say the least.
