The Drama was overall good, the story had me hooked. Who is Big Mouse really? The intrigues during the drama and even the backstory of the important caractars. Every aspect was perfect. The cast was an absolute perfect choice. There wasn't a lot of OST, which could have ruined the mood. So id should deserve a higher rating, but the ending.
The last episode, espacially the last 10 to 15 minutes were rushed.
I'm not shure how big of a time skip there was and how Changho executed everythig (don't wanna spoil). So there is a gap, which I think should have been filled.
But still an overall good drama.
