Entertainment is what the director have in mind when he make this drama, there are a lot of creative funny scene inserted in many situation, and that what's actually make me appreciate this more.
A lot of cliche scene are also inserted purely for entertainment, and they've gone deep with it, so you have to keep that in mind when you watch this.

For someone that want to watch K-drama seriously this might be not for you.

Although they've started with heavy subject (bullying & suicide) in episode 1, they took their time and focus more on the love triangle and FL transformation after she changed with make up until they continue touch it again on episode 10. I do hope they still maintain their comedic tone between those heavy subject scene, and can wrap it up high.
