They made the plot confusing for nothing, we never got to see how Wan and Kim got close even after what happened with their dads, we had some flashbacks that barely explained something. Also, what's the point of making the dreams look like an important part of the plot if when they discovered both dreamed with each other they talked about it for a minute?
Also, the second couple? Why give us a second couple if they appeared like ten minutes in 12 episodes? The company shouldn't have promote the series like there were going to be two couples when that's not true.

Acting: 8.5 stars
Almost everyone was amazing, but if we're honest, Fay has the potential but needs to improve how to act some emotions so the viewers can feel what her character feels in every scene, I believe that if she keeps practicing, she'll become an amazing actress.

Overall, the series wasn't bad, but it's not memorable either, the chemistry between the main couple saved many episodes and the whole series, not the best work of Idol Factory, but I hope they give this pairing another chance with a well made plot.
