5 out of 5. I watched it twice last 2018, then watched it again last 2019. I missed the characters specially the main ones being well-played by my favorites, Seung Gi and Min Ah. I have never seen such perfect series until I found myself watching the 4th time, this year. They made me laughed, cried, smiled, and most of all, the series itself had helped me realized life’s vital lessons and that human love knows no boundaries. The lines are delivered well by each actor that they made my brain leaped into something which inspired me to create things where imagination is the limit and at the same time had my heart broken for each spiritbreaking scenes that I was able to memorize lines in each episode as they had left bold marks in me so much. The whole series was really perfect! Looking forward to Min Ah and Seung Gi being paired again in a new movie or series. Moreover, the staff behind this truly did a great job all the way until the end. Thank you for your wonderful creation♥️.
