Looking for book recommendations where time travel plays a major role. Bonus if there's romance involved. I especially love stories with limitations, like if the character stays too long in the other time or world or they can never return and end up trapped there. The more emotional or intense the consequences, the better. Please suggest books with that kind of thrilling time trap element.
(Recently watched a kdrama called "King eternal monarch" with a fantasy and time travel element and that inspired this idea, I really loved it)
