I loved this drama special - the description is a bit misleading though - I thought it would be about a evil twin and a good twin but it wasn't; it was mostly about misunderstandings of the younger twin and how much the older twin loved and wanted to protect his younger twin. It was full of action, drugs, cops....I cried a lot - but make sure you watch all the way up to the very last seconds. Cast: was so good - the actor who played the teens and the one who played them as adults - they know how to act! Eunchang was my favorite character <3 I will definitely re-watch this drama special again - I think I'm going to download it too! It's definitely worth your time.
