It honestly could have been really nice if it wasn't for the fact that it makes no sense... The acting's good and the actors have great chemistry but those two alone can't make up for having everything else missing.
The beginning's nice. I enjoyed the premise and Ki Jin and Yeong Woo are both interesting characters. But the more it goes on the more it feels like entire scenes are missing. The last two episodes, especially. There's at least 4 scenes missing to make sense of whatever the hell is meant to have happened. Episode 7, I thought okay... let's see if episode 8 can make sense of what happened here only for episode 8 to leave me with even more questions... It's frustrating to get attached to characters (even just a little bit) and not understand why they're crying, why they're mad, why they're not mad, why they're making up, who's to blame, who left or didn't leave, how much time has passed, these are genuinely all questions I have since finishing this series. That's too many questions.
