Now I'm not gonna lie I did watch this purely for Dong wook and hajun but I wasn't expecting anything less since they are both amazing actors. This show is so so so good. It's so funny and so engaging I couldn't stop watching and ended up just binging it in two days. You will not be bored watching this show I guarantee. They balance out seriousness and humour so well that at one point I was so sad and then less that .3 seconds later I was laughing. They even put just the right amount of romance in it but not to much as to take over the whole purpose of the show. It was a satisfying amount. I really enjoyed this show and would highly recommend it to others if you like comedy and crime dramas.
