When do Hermione and Ron kiss?

Hermione and Ron don't actually kiss in the books. Their relationship is implied, but they never explicitly share a kiss. The closest they come is in the final chapter of "Harry Potter and the Deathly Hallows" when Ron returns to the battle and they share a "long, lingering look" before the events unfold.

It's important to note that this is different from the movies. In the film adaptation of "Harry Potter and the Deathly Hallows – Part 2," they do share a kiss after the battle is over.

So, while they don't kiss in the books, they do in the movies!
