If you know about 'Lord of the flies', this has the same vibe but BL. Everyone is flawed and very toxic in their own way, all has their selfish motives and reason. So if you're not into that, turn away..
Hmm based on this work's novel raws, all the characters aka the students are constantly fighting for power dynamics. And based on that idea, the closest vibe another work could have with this would be Caste Heaven as it is also in a school setting tackling the same power rankings between students. It's an old work so I'm not sure if you already heard of that but Caste Heaven is this but toxicity level cranked much higher so beware (≧∀≦)
Snickers scene reminded me a lot of their commercial. It's like tae gun saying to him 'your not you when you're hungry' when he insisted giving that to him
(≧∀≦)
Omg! This had me lmfao even though I know this was such a serious chapter ...
