First of all don't be disappointed if you find no love angle here as it never promised so
It's completely based on problems generally faced by high schoolers where they are to leave teenage and enter twenties

There are in total six cases out of which one case is the base of whole story and others contribute it
The major case starts right from the beginning of series and ends where the series ends
The series deals with problems like bullying homosexuality, unwanted pregnancy and dreams that parents don't support

It is very deep, enlightening, funny and amazing
This drama is so underrated and non famous
I am glad that I came across this

Just watch it for an unforgettable fun

There are five girls solving cases ,helping people and learning life
Each girl is fun and useful and you'll love them
And there is a literature teacher who helps the female lead but is suspicious and also someone against whom she is being warned

The way the series starts and ends is very unique
The very first scene will shock you and you'll end up saying...what the fuck just happened!!!

Do watch it..this series certainly deserves more
