It starts really funny and entertaining acting, but in the second half action and melodrama take over quite in a boring way. Actors are excellent: the main couple, the second male lead, and WOW to the supporting cast - the bunch of policemen, the aunts in the slum, the undercover agents...And the villain with his team are genius! Despite the episodes being so long, only now and then i felt like fast forwarding. A lot of handsome faces too!
Cinematography was also excellent! Nice angles, nice details...
Despite being a recent drama, it somehow seems classical.
I'd rewatch the first few episodes...
