It's interesting that the drama posits Soo Ji who is middleclass be the one that successfully fights back against the heiress bully Ha Rin. Ha Rin hand selected her to be in her class because of her background, mistaking her for easy to control. Soo Ji's sole familial connection actually doesn't have any thing that can be used against her aside from some easily disproven rumors. Soo Ji is financially stable, has good grades, and her largely absent military father has pushed her to be the utmost versatile independent problem solver for everything other than physical self defense. I don't think this guy will ever understand how neglectful he's been even after seeing what kind of bully she's actually been dealing with all on her own. I really like that Soo Ji is no saint, she just wants to stay in the middle, strategically forming surface level friendships until she can safely move onto whichever new school in the city her dad moves them to next. Even facing the violence that she'll be complicit in enabling in the pyramid game, she just wants to stay in the middle as well, but her conscience is challenged by Ja Eun, and finally uses her brain power for the greater good.

Soo Ji's cleverness and Ha Rin's cunning is a great match throughout the show. Everyone is involved in the plot in an interesting way and I like how there are moments where it shows the light of true friendship in between all the darkness that envelops the class because of the pyramid game. I quite enjoyed the paintball scene where they broke the prisoner game by turning the paintball shots on themselves, but it's not quite realistic that they were shooting each other for fun. Those paint pellets really hurt, especially at such close distance. One of them is for real all kinds of freaky though lol. I like how Woo Ri has her own storyline that goes beyond just being the first victim, but she gets to be a hero too. She tracked Ye Lim's stalking behavior albeit when she was doing her own borderline stalking behavior and broke through her agoraphobia to save her former classmate and later spoke out publicly about the pyramid game. Her brother is nice, supporting his sister and also Soo Ji and the other students as one of the rare adults who care.

Some weak parts of the show is definitely how conveniently Ja Eun gets interrupted every single time she's about to tell Soo Ji what happened between her and Ha Rin that makes her hate her so much. It's so inorganic and obvious of the show to stretch out that plot point. That's very sloppy writing indeed. It turned out that it wasn't even the only reason, so they still had something to reveal at the end. Instead it always looked like Soo Ji is missing some crucial information whenever she formulated her plans. There was no need for the principle to be so cartoony when no one else acts like that. Ha Rin's final play to make Ja Eun watch her die was pretty weak, as is her comeuppance having her adoption dissolved. Da Yun continuing to be abused by her dad who gets to comeuppances like that is the punishment she deserves for being abusive to others. Perhaps that is part of the story where the ones at the very top continue to have their way and new ones like the rich twins that move into the class arrive to replace the top of the pyramid. Soo Ji is ready to take them down though.
