overall this drama is good one and worth watching.i actually watched the first ep and gave up,then thanks to mydramalist and all the review,i decided to continue watching it.i enjoyed watching it after that.but can't help but be bored when i was watching the middle part of the drama and wish for it to be over soon.i was tired of waiting for the drama to end.for me,i prefer reply 1997 more because of the cast and maybe because i think 1997 is more lighter than this one which had more characters and story.21 ep is wayyy to long for me i guess.i really like watching samcheonpo's awkwardness.lol
