Reply 1988 was one of the first Kdramas I've ever watched and to this day it remains my favorite. It's a lovely story exploring the relationships between five friends and their families and taking you along with them. When the series ended, I felt like it was saying goodbye. This series is intimate and authentic, tackling several themes including coming-of-age struggles. Overall, I highly recommend it. It's also the perfect series to watch with your family :)
