I'd say this drama is better for a marathon. they had a great plot, great characters, great acting and a really really great ost, but sadly this was one of those cases where the drama got 12eps because they knew they couldn't drag it more..

the cinematography and the vibes/color scheme of this drama was so fitting and so pretty, it set the right mood, it was kinda dark and cold, I really liked it.

I think, beside the ending, my favorite part was the characters. Im Jin Hee was such a normal "mature" and independent woman, they gave her a solid background, she was happily normally married, she had a job she worked hard in and she wasn't randomly "good" or "bad", they didn't add unnecessary conflict to her personal life, but they gave her a small trauma that was like the driving force for her relationship with So Jin.

Sung Joon, although I highly appreciated that he was her "normal" husband that was a cutie, he did seem a little useless, basically though the writers tried to leave all of the "mystery" solving to the ladies and so the cops were basically dumb ;P but again, I appreciate his last smart moves, they redeemed him well.

Baek So Jin was the highlight of this drama, again I think the writers (and the actors) did a great job making their characters feel believable and fresh, Baek So Jin was angsty without being hateful, hurt without having a "screw the world" mentality, and she was so brave, so tiny yet she tried to look uncaring ;(

I can't talk about how much I loved the ending, it was really well wrapped, though I do wish for a 2nd season~

the ost was another great mood setter, and I never rewatch things so it's either a 1 or a 10 ;)
