I stumbled upon this drama while browsing on Viki by Rakuten. The synopsis looks interesting enough and it only has 12 episodes with 45 minutes each. So I gave it a try. I ended up binge watching this drama in 1.5 days! The story is nothing new. The main theme of the drama is about infidelity. But they way they tell the story keeps you curious and interested with the plot twists and turns that I hadn't expected. I didn't like the ending though, it's an open ending and will depend on viewer's interpretation. I never like open endings like this (maybe the producers left it like that to have the possibility for a second season?)
