This is a different story from it's sequel so you can watch this without watching the first one. However, for those like me who's really curious who is the 'master' there were decent clues that still connects this second series to the first one. I'll share my conclusions and predictions regarding the "master" on the second part of my review.

Okay, so what can I say about Revenge Note 2? The pattern of revenge is the same but since this 2nd series has longer air time, the story got better since the characters were explored more in depth than the first one. Although, I can say that the first few episodes actually felt slow and also repetitive since the first one already addressed like the school bullying. But then I guess it's just a way to introduce the characters since the settings are mainly at school. The plot is pretty predictable but I still enjoy it anyway. The execution of the story gives nostalgic memories of high school days.

As for the cast, sadly Cha EunWoo is not on this series but thankfully Samuel is here to save the day. (Half joke, half reality) I loved that the main character had more circle of friends and more people around them that allows more exploration that is relatable. Everyone did their part and made their characters come to life well aside from Geum SooJi. (I am damn confused whether it's the character or the actress that messed it up but I don't know what is the goal of her existence. She felt more of like a good student than a bully. But anyway it might just be me.) Another cast that I really loved to see is Ho GooJoon. It gave me that slightest hope that maybe the first and second story will somehow merge into one big picture. (Although, it didn't. I'm still hoping. I know now why a lot of people demands Season 3.)

Overall, I really enjoyed watching this and I had a good laugh once in a while throughout the series that I really think was funny.

For those curious about the "master" I formulated a conclusion based on the hints I've gathered while watching the show. Although, DISCLAIMER: I am not saying that my conclusion is correct. There's no clear proof as well that what I'm thinking is right. I just wanna share this and hopefully know other people's conclusions as well.

On Revenge Note 1, I've concluded it was Ho GooJoon who had created the app for his younger sister. Seeing him in Season 2, make it feel like he really has something to do with it somehow. In this Season 2, there was this scene where Teacher Maeng and Ho GooJoon went to the programming club room of some sort where a flashback of an old member making an app/program of some sort that will help people like 'him' nothing is further specified but that person died and Teacher Maeng promised to continue what he hasn't finished. The app might have been created by several people and not just one person alone. It's most likely that Robin is also involved in creating the app or at least know something about it. Someone is invited to be there and he happened to be not around with his friends to eat lunch. There were also some hint that GooJoon knows Robin. Robin used the same technique as GooJoon in finding clues on a picture (which is via reflection of objects caught on a picture). On one of Robin's artwork on the rooftop, there's also a drawing of lightning which is oddly similar to the app's logo. This theory however go against other people's theory that JaeYi is involved in making the app. For me, JaeYi is just really a genius who knows a lot of things about programming and fixing gadgets.

Some people might ask how the revenge is executed but from what I understand, the app is really working mysteriously like magic. Because almost all of the revenge happens in unnatural way like how they suddenly trip or got soak wet in the water which is completely uncontrollable. They just suddenly become unlucky of some sort.

For any other theories you might have, you can comment it down so that I can read it. :)
