Books with a relationship similar to Nellie and Percival from Little House on The Prairie

YouTube decided to show me clips from Little House on The Prairie and especially clips of Nellie and Percival’s relationship. I looked through the subreddit, but couldn’t find anything that fit.

I would love to read books with a similar dynamic as the two of them as it’s a kind of dynamic I love to read, but I’ve been unable to find a book that hits that sweet spot.

FMC being head over heels in love but sorta bratty and MMC is able to calm her. Bonus points if the FMC is same height or taller than MMC since that was a point between the two of them!

Any books are fine, except for dark romance :)
