It's my favorite korean drama EVER. Nothing can beat this one ever. It's perfect in many ways. It's a crime not to watch and even greater crime to not like it. It's SO PERFECT! It was so captivating that after 2 years I still haven't rewatched it yet. I dwelled so many emotions and energy while watching it. Just thinking about it makes me happy and bitter at the same time. I made it my routine to listen its AMAZING soundtracks. THEY ARE MAGNIFICENT! I still listen to them every other day. Which is also the reason why the drama still feels so fresh to me. It's a top tier korean drama in every way possible. Watch it and love it. It will leave a big impact on your life and mind.
