Although being the Grim Reaper is associated with taking lives, here we meet a very unique team - the Crisis Management Team, which is dedicated to discouraging people from committing suicide.
In almost every episode, we follow the fate of another unhappy man standing on the edge of the abyss, thanks to which we learn many painful stories. We also learn about the backstories of the main characters, the Reapers.
I think you can learn something valuable from every story in this series. And cry, so for those who plan to watch this series - I recommend buying a large amount of tissues.
