Short and Simple. Basically the premise of this drama. I ended up staying up one night watching little clips of this drama on youtube and decided, you know what, I'll just give it a go since it is only 11, 30 minute, episodes. It was a simple story about a new high school learning how to stand up for herself and be her own person with the help of the Revenge Note app. Yes there was some romance, but not enough to say that this was a romance drama. Plus I love how they made it seem like there was going to be this love triangle with Eun Woo's character, but dude was barely in this drama except for to let us know that he was Ho Goo Hee's almost first love growing up, but how Ho Goo Hee was Eun Woo's first love and still was. It made me a little sad when we got a flashback of the moment Eun Woo fell in love with her, but how he never confessed. But hey, I don't know anything about kpop idol rules (even though they had a small ep about what would happen with a scandal) so maybe it was impossible from the get go and why they didn't drag it on or have him fight for her.

I think one of the reason why I was meh about this drama besides it having nothing really special about it was that at the end of one of the episodes it seemed like one of the victims was going to be an antagonist in this drama and maybe fight back and find out who sent out the revenge note hit on him, but literally it was never brought up again. It almost seemed like everything just eventually worked out at the end.
Another thing I wasn't happy about was the main love interest. I mean he was a solid love interest and would always somehow be there when she needed someone, but homeboy had zero personality or backstory so it was hard for me to get on board with him as a character. Him as a boyfriend was cute, but I honestly liked Eun Woo a lot more as a character because at least we had some kind of backstory with him. Realistically, yes, I wouldn't pick Eun Woo because of the whole kpop thing and probs have to wait until after his contract ends, but as a person, he has so much more personality and would talk with her about things (if she wanted to talk about it). The main male lead would literally ask her is she was ok and she would say yep and then they continued on with their day.

I'm curious to see what the second drama is about. I've heard that this drama is "better" than its sequel, but I'm sensing that, that might not be the case personally. We will see eventually.
