what point of view should a romance story be wrote in?

First person!!!! It's better for readers to get a feel of internal thought and emotion and helps the reader connect to the characters more. I for one HATE reading books in third person because the romance seems so distant and it's hard to connect to it.

*written

"WRITTEN

'written'

Whichever tells the story to the best effect.

What POV was used in the last 10 romances you read that were published in the last ten years? The recent and current market will tell you what publishers are producing.

Depends on what story you want to tell.
It is easier to present all sides in a third party POV.
However, you can feel the protagonist's pain or pleasure easier in a first person POV.

Every point of view is possible. If You have trouble deciding think who the target audience is and if You want to please them or go a bit against the current.
