Still super new to k-dramas so... my very first is Reply 1988! This series made me laugh and even cry so much ( I was just expecting a cute love story), and the messages about family, friends, and youth is just genuine and hit close to home (anyone can relate to at least one family/character in the series). I love the 80s particularly because there were so many good love songs! I have been watching as much k-dramas as I can (even though I have to focus on my studies as well LOL).
