This web drama was pretty light and the main characters were enjoyable! The plot itself is predictable but I still enjoyed it because of the main characters. There was little character development and not so much of round characters but it was the relationship of the characters that made the show fun. Although there were immature characters that really ticked me off, the others made up for it like the brother and Eun Woo. Overall, I'd recommend the drama for teenagers or young adults who just want something light. The mystery of who is behind the revenge app also drives one's curiosity as well so it was also something to look forward to in every episode.
