What is a grumpy sunshine trope?

You might have stumbled across this guide and thought, what in the world is a “grumpy sunshine?”

Well, you wouldn’t be the first, or last person, to ask this question.

The term grumpy sunshine is used to describe an opposites attract romance book in which one of the main characters is a grumpy, ill-mannered, or bad-tempered person, who falls in love with a bright, happy-go-lucky sunshine person.

Usually, grumpy characters are quiet, reserved, stoic, or even icy and sarcastic, and prefer living life by routine and order.

The sunshine characters tend to be outgoing, extraverted, overly friendly, and nice, and see the goodness in everyone and everything.

Usually, the man is grumpy and the woman is the sunshine, but this is not always the case, as you will find out with some of the suggestions I have for you.

It’s a heartwarming, opposites attract combination.
