Best family drama

this is the first time a m writing a review, sorry for all the mistakes.This will forever be in my top most favorite korean dramas, The plot was amazing ,amazing storyline, it started with the 2 main characters , the teens, soon it expanded to a multitude of other characters , it gave an indepth understanding , I personally really enjoyed this dramaI SERIOUSILY FEEL THAT THIS DRAMA IS SO UNDERRATEDthere was times when plot was a bit draggy but after sometime it all made sense, there are many characters and the drama is also able to portray their lives too , without feeling bored, I am so glad I watched this drama
