What is the logic behind your choice of words?
At first I was trying to be "deep" or just "summing up" simple titles, but then I realized the names weren't exciting enough. So I decided to go for teasing titles.
Example:
A chapter previously called "The Day After" is now "There's a Man in your Room!"
Another chapter that's about the bad guy manipulating the MC to believe he was trying to help her bestie, is now "Eun Ha, what are you doing next Friday?"
And so on.
Then I started wondering how other authors pick their titles.
Mind to share?
