Be honest, are you considering this show because Cha Eun Woo is listed as having a main role? Sorry to disappoint you, but I'm sure they did that to get people to watch. I love every scene that he is in, but he suddenly disappears in about episode 8 with absolutely no explanation. It was also good to see the whole group Astro - though it was only for about two minutes.

The other thing that irritated me no end, the FL kept wondering, throughout the whole show, who the author of the Revenge Note was, and the author was never identified.

I really liked Kim Hwan Hee as the female lead's BFF. She was so cute, supportive, and smart.

I understand that bullying needs to be involved in order for there to be a need for a Revenge Note, but I felt the bullying was way over the top. Each time there was an opportunity for a Revenge Note, the scenario was pretty much like the previous one. You might not be bothered by this if you like shows like Mean Girls, but that's not my cup of tea. Add to that the fact that the FL was extremely weak. I just wanted to tell her to stop being such a doormat.

I did not enjoy the overabundance of bathroom humor. It was unnecessary and completely uncalled for.

The romance was so tame it was actually boring.

I know I'm probably going to regret this, but I'm going to watch the sequel, in hopes that it is better.
