24 K-Drama Couples with the Biggest Age Gap

Who has never rooted for a ‘Noona-Dongsaeng’ relationship? Clearly not me. Whether the age gap is emphasized in the story or not, I can’t help, but liking the always more diverse couples who appear in Dramaland. Not to mention that a big age gap is never synonymous with bad chemistry. On the contrary, some leads in the list are clearly recognized for their on-spot portrayal of characters in love.

Moreover, to make it even clearer that age is just a number, I have selected couples who have a gap that is equal to or bigger than 10 years. There are naturally many others in Dramaland with a lesser gap, but it would probably take another article to tackle them.

So, here are 24 K-Drama couples with the biggest age gap. Who’s your favorite? Let me know in the comments below.
