This is one of the best Kdramas i have ever watched.
Each and every character is special and has a variety of traits that make him unique. Even some bad traits are presented with humor but also with respect and they make you fell in love with flawed characters *cause no one is perfect*
This show will make you laugh and cry at the same time. The friendship between the five lead characters is one of the best i have seen and the chemistry is undeniable.
Also the love stories are super cute; we have friends to lovers, bestfriend's sister to lover and workplace romance.
If you like medical dramas you will love it, but even if you are not into them this show will make you fell in love with a new genre.

I recommended 100%
I look forward for season 2
