This s my first review on MyDramalist.  
I remember this drama on second page under top drama in2017 so I decide to register on this site and write  a review. 
I watched Chicago Typewriter weeks before Christmas. Its really beyond expectation.  

Ohh I like  the main actors. I watched Yoo ah in Six Flying Dragon I keen on character he played.
Somehow Korean know how to make a good drama.

Almost forget OST ......yes CT got the best OST ever . Satellite, rhe melody is so lovely  (lyric not that great???? )
I love Boni Pueri. This Czech boy choir is so great. I spent time listen to the ost over n over again on Youtube.
Thumbs up !
