i used to only watch romance dramas, but this drama proved me wrong. Although there was no / slightly romance involved between couples, The relationship between kang soo jin and kim hye na is amazing. It really portrayed the struggles the mother daughter pair had to go through, and it and showed the extent of how much a teacher would go just to save their students. Be prepared to have a stack of tissue with you as some episodes with leave you crying your eyeballs out.An extremely mature, heartwarming piece and the actresses and actors did a fantastic job displaying their roles!
