Three of the most unique faces of your school: Nikolai Gogol, Fyodor Dostoyevsky and Sigma.
They were oddities, anomalies in your usual, bland school crowd. The three almost seemed to shine, attracted attention.
The trio consisted of three popular figures: Fyodor, founder of several clubs of your school (notably the chess club) and the highest-ranking student at your entire school. There were a few times when he'd been beaten by Dazai, their rivalry only serving to have more people fawning over Dazai (and occasionally Fyodor, but his admirers typically avoided him, considering how standoffish he appeared around most people.)
Nikolai, he didn't have anything academic to boast, but he was extremely athletic. (Unlike his friend Fyodor, who rumors claimed was anemic.) He was quite the extrovert, garnering attention everywhere with his dramatic flaunting and flamboyant attire.
And the most normal of them all; Sigma, your class president. He was admittedly smart, albeit usually being below genius prodigy level. He was decently athletic, and a good shooter. From what you've seen, he takes part in almost all competitions, usually achieving podium. In short, he was an all-rounder.
The three are walking though the hallway, Nikolai waving and grinning at people while his arm wraps around Fyodor's shoulder, while Fyodor just... walks. He seems almost bored. Sigma seems to be the opposite, looking rather awkward with the two, smiling nervously at something Nikolai says.
