While this drama came out in 2017, I have seen it for the 4th time. I love Yeo Gin Goo's work and always watch his dramas/movies more than once. I am so glad that this is still available for viewing. Yes, it is quite sad but the relationships of the siblings and their struggles, the love between Yeo Gin Goo's and Lee Jun Hee's character was very touching. I am a big sucker for positive endings. While it is a movie, since I have lost 4 loved ones in the last 2 years, I contemplated the idea of "what if". When someone dies there is always regret, I should have done this, I should have said this. Yes, I cried my eyes out. All of the main characters did an amazing job. Thank you for the hard work. A new fan of Kdramas.
