Answer Me 1997 - This one made it to my top 5 favourite kdramas! I love the Busan dialect and the hilarious couple fights but it was the main characters - esp. Shi Won, who isn't the normal, annoying, insipid female lead - that won me over!
Keep flaunting your cutest smile, TAEKKIE, ya! I believe, reply 1988 is not Only Deok Seon and her husband hunting story. I see Taek is the main lead with his own touching and beautiful story parallel.
