This is one of the best kdrama i have ever watched! They are not enough words to describe this drama, it is just amazing!
I wasnt sure about it when i watched the trailer but after episode one, the drama won me over!
Everything about it its just so real and painful but in a very beautiful way, if you watch it you will understand what i am talking about.
The storyline was so powerful and there was not even one episode that i didnt like, i loved them all and all of them teach me some very meaningful messenges.
This drama talked about very serious matters with a very respectful way and they didnt try to make them look nice, which is very important, some things are just bad and they have nothing nice on them! It had a variety of issues that each episode portrait, for example eating disorders (anorexia), bullying, death, war, rape, mental health issues etc and the most important suicide.
The drama is based on suicide (so please be careful and watch the trigger warnings to make sure you are safe).
Aside of great plot, it had great characters as well. Characters with depth and development, that made you fell in love with them. Each of them (even the side ones) had their own backstory that you got to explore, heartbreaking stories that reminds us that everyone has problems and things they suffer from (always be kind). All the characters were so different but somehow they just create amazing bonds, the chemistry they all had with each other was impressing.
It had a love story too, a very painful yet healing story, that describe what love means and how sometimes in the end you cant fix every crack on a broken glass but you can still try ( i am glad they let an open end to them, i would like to think that they end up together eventually).
The acting was great too, i had some fears for Rowoon, cause i am not a big fan of his previous jobs (his acting in them) but i was happy to be surpriced, he did an exeptional job here. All of them did a great job.
The drama can easily have a second season! And i would love to watch it. I think i am not ready to say goodbye yet!

Overall, i think this is an unbelievable good story that everyone should watch (please like i already said, mind the triggers, because there are a lot of them). It is a very hard and real drama but at the same time so beautiful and healing!

I highly recommented!
