It's ok. It's not that I regret watching it but it could have been a bit better. I always found it weird that everyone could enter their house. It was always open. i wish it had much more Gone Girl vibe.
10/10 great drama. Hidden gem. Both FL and ML are amazing in it. Funny and touching! Thank god there was no milioners in it! The only thing I didn't like was Ki Do Hoon's acting. He's not a very good actor sadly.
