I loved 18 Again! It was a bit heartbreaking at first but soon changed to be a major heart-warming drama for me. It had also some sad, yet cute/funny moments; which I absolutely enjoyed. All in all, it was a great ride, with brilliant actors and amazing chemistry (especially with the presence of a huge age gap)! I think you will not regret watching this. I cried at some points when the main character got to the point of not being able to go back to normal. I'm personally a fan of age gap dramas since there's more tension going on between families and characters but I was delighted to see scenes that had chemistry in them yet kept their boundaries because of the age gap (though they've kissed multiple times rip). Again, you should really watch this drama! It was fun and emotional to watch. :)
