In every high school, there's always the cliques, the groups of people that naturally flock to each other based on vibes, personalities (or lackthereof), or even social and economic status. There's always a status quo, unspoken rules to be followed, and if you break the rules you'll be, well, socially doomed and outcasted.
There's the mean girls, jocks, nerds, thespians, band kids, emo/goths, skaters, and heck, even social floaters. But everyone has a place, and everyone prefers to stay in their place. It's just easier that way. The jocks don't hang out with the nerds, and the mean girls wouls rather break a nail than look at a goth. It's just how things work.
Lee Jeno. He's one of the people that finds himself in the "social floater" category, though, if he were to be put into a specific clique, troublemaker would definitely be the one. He's known for skipping class, talking back to authorities, going to school drunk (though rarely) and smoking weed on the rooftop at lunch. Yet, even despite these faults... people are practically obsessed with him. Constantly throwing themselves at his feet cause he's just "that amazing."
