Amazing lead actors but the side actors(asst writers and agency mangers) were not impressive and lack acting, worst comeey from them, i quite impressed with actress nana, Her laugh and voice really adorable, really good acting,

initial episodes were okay, middle episodes were felt like boring and the fighting for jioon by han bi soo and yuzin scenes were unnecessary and boring, it is quite predictable Jooin like Bisoo but whey she wants to date both of them, didn't liked this part,i just forwarded it while watching .

But i profoundly enjoyed the last 2 episodes, amazing from all angles , i thought there will be a tragic ending but yeah it is , then they made it somewhat better, by at the end of final episode where they showed what if Han bi soo didn't disappear and how would they lived their life with all the love, those glimpse of moments was really captivating, from that i understood there won't be next season ,as we already have seen how their life going to be.
But tragically it didn't happen, at least got some satisfaction, but a sad ending, probably many fans would have loved and myself , if he didn't disappear. But life is unfair.
i would say it's worth watching whole season just for last 2 episodes, i felt like really seen what love is. i would never forget those moments

The ending scene of the show was amazing, when Jooin reads the letter written by Han Bisoo , the way it ended really thoughtful one from writer.
The relationships between mom daughter and mom son were at different level, and the friendships between the two moms and record owner was really interesting element and rare to watch.

I really liked the background music it played a key role in the love scenes, i would give a 100% thumbs up for it , definitely will go into my playlist and this kind of music motivates to learn music.

Even though it has more drawbacks in the drama but i am still giving 8 out of 10 because the story line and the lead actors chemistry. if it had some different ending and some comedy by other actors and some changes, The story line has potential enough to became one of the top most korean Tv shows.

"I do understand the writers view, he just want to share what would you do if you have few days time on the earth and ho would you spend your time with your loved ones". The story tells you many life lessons like "Every day is the best day in life, everyday is important, Everyone should experience love in their life". Also from the mom characters you can say how memories are so important in your life and Also when like someone no matter what you should confess your feelings, who knows what could happen?

improvements:

other actors roles and conversations were boring , writer probably concreted on lead actors and their story line .
The scenes between Han bisoo and yuzin were also not enjoyable, ,
could have made these
improvements , the show would have been next level

Finally i would say , Who knows Han Bisoo might have made it back next after 1 year, he probably lived his life marrying Jioona and had an amazing life with lots of love
