I love this series so much! If you love series like Reply 1988 I think you're likely to enjoy this series as well. The characters felt real. I loved their unpredictable background stories and the portrayal of their dark, imperfect human nature that we all can relate to. It stood out so much compared to so many other pretentious, clichéd dramas and movies. Must watch!!! It's a well written drama, and directed well too. All the tease, twist and cliff hangers were perfectly done without giving me a chance to get bored nor completely devastated out of confusion. I thoroughly enjoyed both season 1 and season 2, and I'm eagerly hoping for season 3 to be made.
