I love a good J-drama because it is a lot shorter than most K-dramas and for one thing, they don't ever drag the story. This drama was based on the true story but I don't know how much it resembles the true event that happened but it sure got at 1 litre of tears from me or 2 litres even. I can't say anything without including spoilers just that if you want some sense of reality and how much you should value the people around you and your life, just watch this. You won't be disappointed.
