Kdramas really do need to not put on really ambiguous titles as their English official titles, because I wouldn't have started watching this fun show if I haven't bothered to read about what the story was about actually. I rarely watch much School-type unless I happened to have nothing to watch and it was on TV, which was how I managed to watch the ones I already did. This drama had a similar vibe with Who Are You: School 2015 so I ended up really enjoying this. Not many school kdramas had the revenge theme as the main plot after all, like sure there's always the many inner issues that will get involved but not like this.

Yanno, even after watching Ruler and Seungho's other more recent works it still felt surreal to see him playing older characters, haha. Since he still have that boyish look on him, but I guess it gave him the advantage of still being able to play teenage roles alongside the older version of his character convincingly enough without needing to have a younger actor playing the teenage counterparts. And I still love how the drama can't stop gushing about how handsome Boksu was and it didn't feel out of place. Seungho really brought out the many charms and great quality of Boksu despite his many flaws, and you can really get why people tend to love Boksu even when he's not quite so bright.

I used to watch Jo Bo-ah and especially Kwak Doyeon play older characters in other dramas to the point that I almost always forgot that Seungho and them don't really have very big age gaps between. Have to say that Boksu and Soojung look good together and their love story was pretty cute. And this was the only few times I don't really mind the whole teacher-student couple tropes.

I really love the many supporting characters, especially Teacher Park played by Cheon Hojin who cared a lot about Boksu to the point that he act like a father to Boksu who grew up without one. It's really cute to see Teacher Park being so bashful to Boksu's mom to the point of being adorable.

I really love the many comedic moments; like how Kyunghyun had this internal radar where he could sense his old homeroom teacher approaching him, the funny CSI parody as well as them training the kids to study as if they were trying to train kungfu under Master Wong Feihung's lead. And I love how each even-numbered episode would end in a dramatic tone as the plot progressed towards unexpected outcomes and made one eager to anticipate what happens in the next episode. It really felt like watching really long but engaging movie.
