The plot is quite interesting, it is based on a revenge note. However as the story progress, the story does not explains or explores at least a little bit where this revenge note app come from, who created it, for which purpose. At the end, she decide to delete the revenge note app from her phone because she thinks she does not need it anymore but does really not give more details as to why now she does not need this. For the romance part, the end with the second main male lead was unsatisfying. From my opinion there were major loopholes regarding the revenge note application and the second male lead.

I found Park Solomon was the best among the cast. I have watched this drama for him to be honest. And sorry but I think the main female is lacking acting skill. Eunwoo was overall good, but he did not appeared a lot in the drama so we cannot really 'judge'. And to be fair, I wanted him to appear more often in the drama, so I am a bit disappointed because of that. He is a good actor aside of that.

The music was good, I particularly like the rap ost.

Overall, it is funny, light and I suggest you to not have high expectations if you watch it.
