I don't know why people are complaining about this drama. I currently find it really good and have enjoyed every single episode that is currently out. I am totally not disappointed in Lee Yoo ri's acting, she is just an amazing actress. I hope they do not ruin this series and it continues the way it is.
The whole drama is actually pretty shit (no offence), the main couple has 0 chemistry. However, the second couple makes it worth the watch. I wish the drama was all about them, i really didnt care about any of the the characters. But i recommend you to watch it just for chang soo and ji yi
