This show is the first show that made it absolutely an obligation for me to leave a review. 4 years watching korean dramas and having watched a crazy amount of them, this is the first review.
IT WAS AN HONOR TO WATCH THIS SHOW.

For those who are wondering and debating whether this show is worth it, it took me months to convince myself to watch this considering it's about middle aged men and i'm in my 20's and had no romance, sci fi, thriller tags. but how glad i am i finally did! So please watch this. This is a must watch. There is NO korean drama like this. It's the first of it's kind and i wish with all my heart this becomes the standard of korean dramas from now onwards. this is a therapeutic show in my eyes.

This show is all sorts of beautiful. This show is not about solutions, not about how life should be, not about closure or happy endings or sad endings or a directed story told in a few episodes. This show is a chunk of life shown of people at different stages of their life. This show is the most realest show i have ever watched. It made me laugh and cry. The storyline, the direction, cinematography, the music, everything was just perfect.
This show not once glorified life. It showed it how it is. That's the beauty of this show.

The emotions in this show are so overwhelming it's crazy. I felt so attached to the characters it's so sad this show ended but what an ending it was. It makes me believe. Makes me hope. It taught me so many life lessons. Seldom is a show this beautiful made that encapsulates life so beautifully by keeping it 100% real.

The love in this show is the most deepest i have ever seen in any. It is a show with the most meaningful love and it didn't even have to be a romantic drama. Everyone can interpret love differently for this show. I choose to interpret it as love between a man and a woman who felt their souls being attracted to each other. Without any skinship, any cheesy romantic words, this show was able to show the love that if one finds it in life, they have it all. The most purest of all loves. The two souls who met each other in their most broken states, healed, filled each other despite. Souls that helped each other grow. The love in this drama is unlike any other. Most deepest, most heartfelt, most relatable.

The cast was beautiful! absolutely perfect. the best acting i've seen. IU's role was so different than her previous ones and she proved how good of an actor she is. she was FANTASTIC. Lee Sun Gyun was a treat to watch. This was the first i saw of him ever since Coffee Prince and i knew instantly why back then i had a second lead syndrome. He was INCREDIBLE. His every nerve expressed emotions. His eyes spoke millions, his walk, his talk. He was a show stealer. Plus, he has the best voice ever. Calms your soul and his character with that voice just melted me. (considering i'm in my early 20's, Ahjussi, saranghae :P ) .

VERDICT: WATCH THIS SHOW. LEAVE EVERYTHING AND WATCH THIS SHOW. this show is LIFE!

Thankyou screenwriters, producers, directors, the entire cast, the entire team behind this show for making one of the best shows ever and thankyou for giving us this masterpiece that is full of life lessons. I repeat, it was an absolute HONOR to watch this show.
