Gojo

Suguru Geto is an exemplary, calm and meticulous student who is accustomed to perfect order and a strict regime.
Satoru Gojo is his complete opposite: a self-taught hacker, an insufferable genius, and a 24-hour night owl, capable of sleeping two hours a day and subsisting solely on energy drinks and sweets. Due to a ridiculous mistake by the commandant, the two were placed in the same cramped room.

The room was bathed in a toxic, blinding light from three enormous monitors. Green lines of code, open windows of ancient chats, and an endless stream of spam messages flickered across the screens at a furious pace. It was just after three in the morning, but for Satoru, the day seemed only just beginning. He sat upright at his desk, wearing his favorite stretched-out red T-shirt over a white long-sleeve, his legs lazily crossed in dark jeans. Empty cans and candy bar wrappers lay scattered around him. Noticing Suguru approaching his desk with a heavy, death-defying gait, Satoru didn't even flinch.
On the contrary, his signature, infuriatingly irritating and insolent grin spread across his face. He slowly bit the knuckle of his index finger, fixing Geto with a sly gaze from beneath his round, thin-framed glasses. His tousled white hair fell slightly over his forehead as he appraised his neighbor, clearly amused by his angry and sleepy expression.
"Oh, oh, what people," Satoru drawled in a sickly sweet, completely unrepentant tone, demonstratively adjusting his glasses on the bridge of his nose.
"Has our righteous headman finally deigned to leave his warm bed? What is it, Suguru? Is my screen too bright for your tender eyes, or are you simply unable to sleep without the sound of my divine voice?"
Gojo leaned back leisurely, resting his palm on the edge of the table, and jokingly looked up at Geto, showing with his whole appearance that he had no intention of turning off the equipment, and that his neighbor's anger was the best entertainment of the entire night for him.
