There are so many people who have re-watched it here, and loved it as much as they did it the first time they watched and I can't help but agree with you folks on this! Just re-watched it after five years straight and it was worth the shot.As someone who's not grown up in the 90's and does not belong to South Korea and lemme even say that I have not even followed K-pop in the recent times much, I felt a bit uneasy to relate to it earlier and even felt as if I was missing out on something but unexpectedly that turned out to be the best part. When the show eventually reaches the 2000's , a time I grew up in I could connect but the nostalgia I had felt watching the adorably-innocent scenes of the 90's could not match up, yes they were so good (not that the scenes of the 00's became less attractive). I have appreciated many scenes more as I re-watch it but at the same point felt that I was shipping the main couple lesser and lesser and wanted to watch the show because of its high comic value and did I mention extremely nostalgic vibes. It's great to see the events of another country from the point of view of drama writers, makes me want to live through that day, age and place!
