This has seriously been one of my favorite dramas. As an avid reader and a drama lover, this drama has tied those two aspects really well.

I simply loved the way the cast portrayed their love for reading and books. When I watched this drama I could relate to their love for books. I feel that this drama had the right amount of focus on books, reading, drama, and comedy. It didn't focus solely on one aspect and for me, that made this drama so much more enjoyable.

I love how the protagonists just connected with each other. Each of the cast's characters had a unique personality, even the characters that seemed to have a perfect life had some sort of struggle, which I feel made the characters more human.
The casting was done really well. Some of my favorite actors like Lee Jong Suk made this drama a must-watch. All the cast members including the protagonists and side characters each made this drama more memorable and enjoyable.
The ending of the drama wrapped up wonderfully but made me sad that it was ending.

I would definitely recommend this drama to anyone and everyone. I promise it is worth your time
